A group of teenagers, in an attempt to rescue their friend from an evil corporation, end up inadvertently releasing a horde of bloodthirsty zombies.

The scientist of the powerful and evil corporation Hybra-Tech Charles goes to Chernobyl to buy some gallons of toxic waste to perform experiments with zombies. When a teenager has an accident with his motorcycle and vanishes, his teenager's friends, leaded by Charles' nephew, find that he was moved to Hybra-Tech. They break in the facility trying to find their friend and accidentally release a group of zombies starving for brains.—Claudio Carvalho, Rio de Janeiro, Brazil
