In a remote Pacific island, a top-secret military experiment is underway to develop an ultimate anti-toxin, led by Dr. Andrea Swanson and her research assistant Jake.

The crew soon finds themselves fighting for survival as a breed of mutant snakes, including a giant diamondback, is released from their containers and begins to stalk and attack them.
