The CEO, Burton, seeks out Dr. Vera Collins, who's researching breast cancer treatment using the vipers' venom. As the vipers wreak havoc on the island, newcomer Cal Taylor, a former army veteran, leads a group of survivors in a desperate bid to stop the deadly creatures and uncover the sinister plans of Burton and his chief of security, John Staffen.
