Ten years ago, an Army research post on a remote tropical island was decimated by a strange new virus. A team of Navy Seals is sent in to investigate. That team is not heard from again. Now, when a recon team arrives to rescue them, they must deal with an onslaught of zombies. As they fight their way to the old lab facility, they realize that the military physician in charge of the research station is still alive and still experimenting. Both the deadly virus and the deadlier zombies are his creation, and every new wave that the team faces is more vicious and ghastly than the one before.
