Soldiers sent to investigate a chemical accident at a research facility find themselves battling a horde of flesh-eating zombies unleashed by an experimental nerve gas, and the outbreak's origins are eventually traced to a remote jungle setting overseas. Directed by Bruno Mattei under the pseudonym Vincent Dawn, the film is infamous even by Italian zombie-cash-in standards for its shameless recycling of stock nature-documentary footage and its Goblin score, which was lifted wholesale from Dawn of the Dead without permission.
