In a world ravaged by a zombie apocalypse, the remnants of humanity are divided between military personnel and scientists, holed up in an underground bunker in Florida. The scientists are desperately trying to understand the cause of the outbreak and find a means to control the undead, led by Dr. Sarah Bowman, who is determined to find a solution. Tensions run high as the military, led by the unstable Captain Rhodes, grows increasingly impatient with the scientists’ lack of progress, demanding results that could lead to their salvation or an effective method to exterminate the zombie threat.

Amidst this tense atmosphere, Dr. Logan, a scientist nicknamed "Frankenstein" for his unorthodox experiments, believes he can domesticate the zombies, thereby finding a way to coexist with them. He focuses on one zombie in particular, "Bub," who shows signs of human behavior, suggesting that zombies might retain some memories from their previous lives. This discovery sparks hope but also leads to further discord within the bunker as ethical and moral dilemmas arise. The fragile balance between the military and scientific teams teeters on the brink as external threats close in, setting the stage for a struggle that could either lead to humanity’s salvation or its ultimate annihilation.
