Enredo

A set of vipers has been taken by the scientists, when the vipers escape into the woods, they do more than just bite.

There is a break in the Universal BioTech laboratory and vipers escape. The CEO Burton seeks out Dr. Vera Collins, who is researching the healing of breast cancer using the vipers' venom, and tells that the secret facility was researching enhanced vipers to produce more venom. Meanwhile in the peaceful island Eden Cove, in the Pacific Northwest, the vipers attack the residents. The newcomer Cal Taylor, who has come from the army, leads a small group of survivors to attract the vipers and save the locals from complete destruction and they discover an evil plan of Burton and his chief of security John Staffen.—Claudio Carvalho, Rio de Janeiro, Brazil

In high hopes of finding the cure for cancer by using the deadly venom of genetically modified horned vipers, instead, the ambitious scientists at a remote medical research laboratory only managed to increase the reptiles' aggressiveness. As a result, after a botched attempt to break into the seemingly secure facility, a band of thieves unwittingly release the mutated snakes in the nearby island of Eden Cove, and before long, packs of enhanced serpents start attacking the unsuspecting residents of the fishing community. Now, there are more snakes than inhabitants. Can they survive the vipers' deadly bite?—Nick Riganas

When some genetically enhanced vipers are released during a break-in at a medical research laboratory, it results in plenty of slithery problems in this terror tale. As the sinister snakes eat everything in their path and reproduce at an alarming rate, a group of locals trapped in a hotel on an isolated island tries to escape."
