When Zoey and Kiki, two irrepressible girls from another galaxy and world called Lumina, land in Lightning Point, their dreams of surfing the waves of Earth's oceans and seas have finally come true. As soon as their spaceship lands, they head to the beach where they meet Amber, a local teenage girl teaching a surf class. Zoey and Kiki convince her to give them a beginner's lesson, but when Zoey borrows Madison's board and surfs the back break, Amber is suspicious.

With their spaceship obliterated and no other way of getting home to Lumina, Kiki and Zoey settle into the teenage world of Lightning Point at Amber's house. Amber's mother, Olivia Mitchell is surprised by the girls' sudden appearance, but is glad Amber finally has some company. Amber hopes Kiki and Zoey can keep a low profile, but her dreams are dashed when local surf king Brandon takes quite a romantic interest in Zoey and invites her to a barbecue at the request of his girlfriend Madison.

To blend in human society, Zoey and Kiki start attending Amber's school and find it nothing like school on Lumina. In a desperate attempt to contact home, Zoey devises a plan using "primitive" Earth technology: satellite dishes. Convinced that this plan will work and that human hearing can't detect the signal, Zoey and Kiki plant their plasma card on the school satellite dish and beam up a signal.

When Kiki is moved to tears by Amber's singing, Amber makes an important discovery: Luminans do not natively experience feelings or emotions, but Zoey and Kiki's human bodies can. Meanwhile, Zoey has fallen in love with the sport of surfing and goes out every day. That is, until Brandon steals her wave and makes her break Amber's prized surfboard. Having never experienced the feeling of anger, Zoey is a ticking time bomb and when Brandon and Madison team up to push her buttons, Zoey unconsciously starts creating miniature earthquakes around Lightning Point.

Quadrupeds fascinate Kiki and when she finds out that Luca's horse Bandit has been skittish and dangerous to ride ever since they arrived, she feels terrible. Secretly using her alien abilities, Kiki reads Bandit's aura and calms his life-force energy, just in time for Luca to see that Kiki and Bandit now have a special bond of strong friendship.

Luca and Kiki have been growing even more romantically closer, and Amber is sick of being stuck in the middle! Finally, Luca asks Kiki out on a date, and Kiki can’t wait. Zoey thinks that romantic love is a waste of time and sets off to follow up on some plasma card research, which may help unlock the mystery of why they came to Lightning Point. When Kiki arrives for the date, Luca is surprised to see that she brought along Amber.

Zoey is finding Brandon a challenging surfing adversary. He's even started to compliment her on her moves. But there's one person who doesn't like this change in Brandon: his girlfriend Madison. Zoey is feeling on top of the world, so when Madison casually challenges Zoey to surf the infamous Lighthouse break with her, Zoey accepts.

With Luca and Brandon dangerously close to their secret, Kiki feels that they have no choice but to stick close to them, to find out what they really know. So when Madison throws a birthday party for Brandon, they have no choice but to attend. Madison is hoping to win Brandon back with her spectacular event, but when Zoey and the girls arrive, her hopes are crushed. Brandon and Zoey are finally having some time alone where Brandon admits to her that he’s adopted and feels out of place. Zoey learns they have more in common than she first thought.

Zoey is sick of waiting and decides to take charge of finding a way home. Back at the cane field, Zoey and Amber test out the energy field one more time. It wasn't just there to unlock a symbol; it’s a signal pathway that goes straight to Lumina! But while Zoey and Amber are completing their tests, Brandon spies a mysterious energy cloud over the cane field. Before Zoey and Amber can react, Brandon barrels through the cane.

When a storm is forecast to hit Lightning Point, Zoey and Kiki know it’s time – they can send a signal through the lightning, via the energy field and back to Lumina. The trio is sad that their time together is coming to an end as they prepare to leave. But Luca Benedict and Brandon, buoyed by Brandon’s recent sighting have a plan to catch the aliens. When the storm comes they will be ready. As Amber watches the girls send their signal through the lightning, she stumbles backwards. Energy detectors?

Kiki and Zoey are anxious – with no reply from Lumina and Luca knowing who they are, they’re no longer safe in Lightning Point. Suddenly, Sergeant Mitchell gets a call from the local police station. There’s a disturbance at the cane field. Maybe this is the signal they've been waiting for? But when the girls arrive, they don't see the type of ship they were expecting. A fishing boat, in the middle of the cane field! What could it mean? And how will this get them home?

Amber is totally excited when her crush, Josh has noticed her at school. She’s doubly excited when he asks her to help organize a Hawaiian fundraiser party for his basketball team. But when Zoey runs late from a surf lesson with Brandon, Amber accidentally stumbles into Zoey’s plasma recharge. Suddenly, Amber starts affecting gravity.

Brandon is furious with everyone – and especially Zoey – for lying to him. How could they keep a secret like this from him? And how could the Luminan people, Zoey and Kiki’s people, abduct his parents?! When Luca tries to calm him down, Brandon’s temper flares – and starts a fire in the middle of the cane field. Luca’s horse Bandit is spooked and bolts through the forest, carrying Luca with him.

Brandon is so excited by his alien energy that he starts to recharge more frequently than he should, causing too much of an overflow in his Lumian abilities. Suddenly, in the Diner, Brandon can’t help but radiate energy out into the atmosphere – which starts to affect the Diner in supernatural ways.

Amber, Zoey and Kiki take a last surf of Lightning Point’s waves. Zoey and Kiki will miss this place – and Amber – when they leave for Lumina tonight with Brandon, who is in search of his Lumian mother and human father. But Sergeant Mitchell doesn’t lay off a case easily and just as Brandon is recharging, Sergeant Mitchell discovers his alien technology. Detaining Brandon and confiscating the boat and card, Sergeant Mitchell has put a dampener on the girls' escape, before a hair-raising plan sees Brandon rescued. But with Brandon now on the run, he makes the biggest decision of his life – to give up his powers and transfer his energy so Zoey and Kiki can leave without him.

It’s an emotional farewell between Brandon and Zoey before the real battle starts – getting Kiki and Zoey onto the boat and out to the spaceship. While Brandon creates an extraterrestrial diversion, Kiki and Zoey sail the boat to the lighthouse with Luca and Amber’s help. But suddenly, a lightning storm hits Lightning Point. Will it be too dangerous to risk searching for the ship with their card? And will there even be a spaceship to find?
