Story

Geologist Patrick Osgood leads a mining team through the network of caves beneath the Alpha complex in search of tiranium, a rare mineral which is an essential component of the Moonbase life-support system. The search has personal meaning for him as the metal is needed to complete an artificial heart for his dying wife, Michelle.

Osgood orders an excessive amount of explosive charges deployed to hasten the operation. The hyper-nitro charges detonate prematurely and Osgood is caught in the blast. Semi-conscious, he drifts into the latest in a series of recurring visions he has been having, where Moonbase Alpha is destroyed by a raging fire. The visions begin with the same image: Michelle Osgood, lying helpless in a canopy bed out on the lunar surface. Blazing energy rains down from space and the surrounding Alpha buildings burst into flame. The bed is rapidly encircled by a wall of fire. Unable to move, Osgood shouts for her to rise and save herself. She struggles, but is too weak. Michelle and the bed are then consumed by the inferno.

When Osgood recovers, he is told by his team that there is no sign of tiranium. Disgusted, he proceeds to the Medical Centre, where Michelle is confined to bed. Osgood demands a private visit with his wife. Always a religious man, he has become a fanatic since Michelle's diagnosis of refractory heart disease. He recounts to her his visions of Alpha perishing in flame. She will be saved along with him...but only if she has complete and utter faith in him.

As if fulfilling Osgood's prophecy, the Moon travels into an area of intense heat. Even with full-strength air-conditioning, temperatures in the surface buildings soon average 40°C. With instruments unable to determine a cause, John Koenig takes Eagle One on a reconnaissance mission to locate the source of the heat. After his departure, Helena tests a tenth artificial heart for Michelle. The Dorfman cardiac prosthesis was designed to have valves coated with tiranium. However, the Alphans' supply of tiranium is low and none can be spared for this project. Forced to use less-than-adequate substitutes, Helena is battling her own desperation and the cynicism of her collaborator, Doctor Ben Vincent, as attempt after attempt fails.

When the latest artificial heart fails, Osgood denounces these scientific attempts to give life as blasphemy. After he exits, the doctors debate whether his growing instability is the sign of a breakdown, or, in view of his recent prophetic visions, a more metaphysical influence. Osgood returns to the care unit to visit his wife. At her bedside, he is inspired by the recollection of a past conversation of theirs, where the secular-minded Michelle commented her faith is in their love. After formulating a plan of action, he leaves, convinced he will be her saviour.

Koenig is unable to find a cause for the ever-rising temperatures. He gives Tony Verdeschi command authority in his absence (as the ship will soon pass out of communications range). Helena interrupts to plead for a few grains of tiranium to complete the heart. Koenig refuses: with the strain placed on life-support by the present emergency, the scarce mineral is more valuable than a single life. Koenig expresses his confidence in Helena and her abilities to find an alternate solution.

The temperature in Alpha reaches 45°C on Level A. Verdeschi orders all supplies of the heat-sensitive hyper-nitro relocated to the relatively cooler storerooms on the lowest subterranean level. During the transfer, Osgood unexpectedly charges in. Verdeschi tries to sympathise with his old friend but, obsessed with his role as prophet, Osgood lashes out. He lays out the guards and grabs Verdeschi's sidearm.

A passing Maya witnesses the scuffle. She transforms into a large Alsatian dog and forces Osgood to drop the gun. Osgood runs off and gains access to an explosives storeroom on another level. Verdeschi stations sentries throughout the Medical Section, figuring the geologist will try to approach his wife. While visiting the patient, he turns on the charm, downplaying Osgood's irrational behaviour to spare the weakening Michelle any further stress. Verdeschi relates the details of his encounter with Osgood to Helena. While doing so, he questions why Osgood was at the A-Level explosives storeroom in the first place and orders Security to place guards around the other storage facilities.

Osgood is discovered in a woman's quarters, bloodied and half-conscious. While conveyed by stretcher team to Medical, he experiences another vision: Michelle, again lying in the canopy bed on the lunar surface, surrounded by fire. This time, he can move and tries to run to her aid, but can make no headway. As before, she is too weak to rise and perishes in the flames.

Helena tests an eleventh model of the Dorfman heart, but it fails to function for any significant length of time. Despondent, she is called away to casualty reception. There, she finds Osgood, with multiple lacerations on his arm and weak from blood loss. As she examines him, the geologist reveals a belt of explosive charges strapped around his torso, wired to a deadman switch. He allows Helena to bind his wounds, then demands to see Michelle. He intends to flee with her to the catacombs, before Moonbase is destroyed in the coming holocaust. Knowing that any physical exertion could kill Michelle, Helena begs him not to take her. A new heart is her only salvation and the doctor promises to get tiranium for it. Osgood rejects her heresy, and husband and wife leave the care unit together.

In space, Eagle One encounters a dark nebula. After passing through and out the other side, Koenig and crew make visual contact with the heat source-—an enormous disc of super-heated plasma and flaming hydrogen. The fire-storm is on a trajectory for the Moon, travelling faster than the Eagle's maximum speed. Reversing course, Koenig informs Moonbase that the plasma-storm will impact in the vicinity of Alpha. Helena makes one last attempt to persuade Koenig to release tiranium. His reply is lost in storm interference. She turns to Verdeschi for a decision. He allows her to take what she needs. When Michelle's hospital name-plate is discovered deep in the caverns, Verdeschi goes underground to hunt for his friends.

Intimately familiar with the catacombs, Osgood manages to keep ahead of the search parties. But his exhaustion combined with Michelle's debilitated condition has them resting too frequently. He removes the belt of explosives for fear of blowing them up by accident. He slips into another trance: Michelle is again trapped in the ring of fire. Osgood wills her to save herself. This time, she rises to her feet, drawing strength from their love. He strides through the flames unharmed and, taking her in his arms, they walk safely out of the inferno.

Heart number twelve is constructed with tiranium-coated valves, and functions perfectly. Helena calls Verdeschi with the news and implores him to find Michelle. As he proceeds, the cavern is rocked by a tremendous blast; a super-heated plasma flare spun off from the fire-storm has impacted on the surface. Between the heat and the barrage of plasma streams, Moonbase sustains considerable damage.

The surface explosions cause rock falls and cave-ins in the catacombs, hindering the search. Verdeschi finally sights the fugitives; when he shouts out the news of the heart, Osgood smashes the security chief's hand-torch with a well-aimed rock and the couple slips away in the darkness. To even the odds, Verdeschi calls Maya down into the catacombs. She transforms into a Bengal tiger and guides the search party through the tunnels with her night-vision.

Michelle can go no further and crumples to the ground. The Maya/Tiger corners Osgood while Verdeschi attends to the girl. A blast brings down the cavern ceiling on top of Osgood. Sending Michelle back with Maya and the guards, Verdeschi begins digging his friend out from under the rock fall. The girl is rushed to the operating theatre, where Helena performs the procedure. In spite of the perfectly functioning heart, Michelle's condition remains critical. With her husband missing, she has lost the will to live.

When Verdeschi brings Osgood into the medbay, Michelle's vital signs improve. Husband and wife exchange a loving glance, then Osgood looks ceilingward and declares, "It's over." In his mind's eye, he sees the plasma fire-storm inexplicably veer away from the Moon and speed off into space.

With the temperature back to normal and damage repairs underway, Helena and Verdeschi speculate if some sort primal intelligence existed in the fire-storm, it could have somehow made contact with Osgood's unbalanced mind. If so, this communion could also explain Osgood's temporary gift of clairvoyance.

Eagle One returns and Koenig contacts Helena on touchdown. Welcoming him home, she thanks him for the tiranium. He is initially surprised by this unexpected confession. Her obvious delight at having saved Michelle's life defuses the situation though, and Koenig returns the smile of the woman he loves.

Production Notes

• "Catacombs of the Moon" is a 'Helena Double-Up' script and was produced simultaneously along with "The AB Chrysalis". Series regulars Barbara Bain, Tony Anholt and Zienia Merton carried the majority of the action. Martin Landau's brief scenes were confined to the Eagle command module; his only interaction with Bain occurred via TV monitor in the epilogue. Catherine Schell's two small contributions amounted to a cameo appearance. The episode is set primarily in the standing Alpha sets with moderate filming in the Stage 'M' cavern sets originally built for "The Metamorph".
• This episode featured the return of Zienia Merton after a three-month absence; the actress had left the programme after filming "One Moment of Humanity" because of her reduced involvement (sometimes only a half-day's work) and her new non-contracted 'day-player' status.^[2] Merton recounts that Barbara Bain had telephoned and asked if she would consider meeting with Gerry Anderson and Fred Freiberger to discuss her returning to the series. Bain's motivation was that she and Martin Landau would be on holiday for the majority of the shooting of an upcoming episode ("The Beta Cloud"). As this would result in a very brief appearance by the series' stars, the Landaus feared long-term fans would be alienated when tuning in and not seeing any familiar faces from the first series. Guaranteed a more involved role in the series (though still no contract), Merton accepted the offer.^[4] From this time forward, her character was referred to on-screen only by the diminutive 'Sahn' (sometimes 'Sahn Benes' in script character lists).
• In the shooting script dated 18 May 1976, Koenig's co-pilot, Bill, was supposed to be Astronaut Bill Fraser. Budgetary limitations led to John Hug's replacement with one-off actor Alan Hunter. Early drafts of the script had Helena and Ben Vincent referring to their prosthesis as the 'Bergman' heart, as it was identical to the mechanical heart implanted in the late Victor Bergman. One line of dialogue read 'Victor might have lived forever—given the chance.'^[5]

Novelisation

The episode was adapted in the second Year Two Space: 1999 novel Mind-Breaks of Space by Michael Butterworth and J. Jeff Jones published in 1977. The authors made minor changes in the story, the most obvious being the two Maya transformation sequences feature decidedly extraterrestrial animals: a long-bodied beast with natural armour plating and trap-like mouth would come to Verdeschi's aid in the explosives storeroom and later, a headless, bipedal bat-creature would use its sonar to navigate the Security team through the darkness of the catacombs. The novel would also give Koenig and Maya more exposure than did the actual shooting script and transformed the character of 'Sahn' into a young Indian man.^[6]
