"Pamana"

In 1983, four cousins: emigrant Benedict, narcissistic Myra, eloquent Faye and former clergyman Donald gather in their late uncle's house to get their inheritance of 5 million pesos each. Their uncle's butler told them if one of them dies within a month, his/her inheritance goes to the others. Each of them were given the responsibility of taking care of a comic book written by their uncle. The cousins show no interest to their comic books, except Donald, and throw it away. Meanwhile, Benedict is killed by Filomena, a malakat from one of his uncle's comics.

They return to their uncle's house only to find out the butler had died. At the strike of midnight, the characters in the comics came to life. Donald, with the help from Rosalda, a ghostly pianist, had discovers there is an even stronger character, Buboy ang Munting Diablo. Buboy kills them one by one, leaving only Myra and her daughter, Gladys (Anna Vicente), as the survivors. They rush out of the house and board a taxi. Buboy, disguised as Myra's stepson, Filemon, gives her four cheques worth 5 million pesos each. As they leave, the taxi driver activates his cab's sound system to news broadcasts as nearby residents do the same on their own radios wherein they hear a reporter announcing the imminent arrival of the plane carrying Benigno Aquino, Jr.

"Lost Command"

Members of the Philippine Army’s Special Unit 21 led by 1Lt. Bert Garces and MSgt. Martin Barrientos are sent on a mission to against rebels in the remote jungles of Mindanao perpetrated by a certain Kapitan Baltog, leader of a lost command squad now known as Alsa Puersa.

Following the insurgents' trail, the group goes to Barangay Pototan where Barrientos meets Bunag, a villager who claims "undead soldiers" were "recruiting" his father. An unexpected encounter leaves a third of the platoon missing including Garces as the insurgents abduct them. Barrientos decides to rescue Garces and the others, despite Corp. Upaon's suggestion to notify base and get back-up. Bunag volunteers to become a guide.

The group encounters a blind girl, Linda, in the forest and offers to lead them to her father, leader of a group fighting what she confirms to be zombies. Upaon voices his doubts, and could neither radio base nor convince Barrientos to go back. 1Pvt. Conde, meanwhile, supports Barrientos' decision so they push on ahead to a part of the forest that not even Bunag is familiar with.

Linda's father turns out to be a zombie, and has been using his daughter to bring in the unsuspecting new "recruits". An undead Garces shows up, revealing he has retained his intellect and urges the remaining soldiers to join the "new army". Barrientos and his men put up a short-lived stand before they are captured.

Upaon finally manages to radio for back-up before being dragged away by a zombie as Barrientos regains consciousness and meets a zombified vigilante named Col. Rolando Palma, revealing himself to be Kapitan Baltog. He formed the Alsa Puersa, aiming to replace the current army starting with the zombified Special Unit 21. Palma also explains he was zombified somehow due to tainted food provisions. Refusing to accept defeat after being surrounded by the undead, Barrientos manages to rescue Upaon after detonating a nearby cache. However, he is forced to euthanize Upaon who has begun to change after being forced to consume tainted meat.

Meanwhile, Conde narrowly escapes his zombified platoon and finds Barrientos. The two try to escape but get separated along the way. Conde ends up encountering a soldier who can seemingly change into a normal human, and the outcome is left unknown. Barrientos, on the other hand, encounters Linda's father who offers to help him escape in exchange for getting Linda out of the forest. He explains the zombies are somehow unable to cross bodies of water, so he pushes Barrientos into a nearby river before being mauled by the zombified soldiers. Barrientos is found and rescued by an Army helicopter due to Upaon's earlier distress call.

As Barrientos recuperates in a military hospital ward, the nurse informs him that he is not the only survivor of his unit. Garces and Upaon are seen in the beds next to his, revealing that they too can morph. The ending scene shows a zombified soldier attacking a nurse.
