Six graduates of the medical university decided to become forensic experts, for which they went to a small island where they should undergo practical training. They were divided into groups of two people and were given a list of tasks, as a result of which two of them would get a permanent job. Students are not aware that this island is a secret laboratory organized by the government to experiment with prisoners who received life sentences. At one point, something went wrong, and the subjects who were supposed to die survived. However, after the experiment, they were no longer ordinary people, but turned into bloodthirsty zombies .
