Ten years ago, an Army research post on a remote tropical island was decimated by a strange new virus. Now, a team of SEALs on a recon mission has gone missing on the island. When a Strike 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 Colonel in charge of the research station is still alive and still experimenting - the zombies are his creations, and every new wave the team faces is more vicious and ghastly than the one before.
