Vipers is a 2008 American television film directed by Bill Corcoran and starring Tara Reid and Jonathan Scarfe.
Universal Bio Tech Research Facility secretly works on enhancing horned viper snakes with poison C12 for their venom to cure disease.
Aided by his own men, a man named Jon Staffin subdues the staff to steal the snakes.
Meanwhile, a man named Cal Taylor comes to Eden to see Doc Jim Silverton.
Sheriff Tom Hendricks eventually calls Doc, saying that teenager Maggie broke into a store and smoked marihuana.
Meanwhile, Dr. Vera Collins, who works at Universal Bio Tech but only recently learned that the snakes were enhanced, tells Burton, the CEO, that she needs to examine Jake's bite to determine if it comes from one of their vipers.
They get cornered outside the office, but Cal and Nicky again use the extinguisher to deter the snakes while they all hide in a non-functioning van.
They enter a café, but Ellie gets killed, and the rest barricades themselves into the building using ice, inferring that the snakes do not like the cold.
En route to the inn, they use grenades of C12 to subdue the snakes, which eventually manage to kill one of the men.
One of Staffin's men, Lewison, eventually tells the truth, that they were not there to rescue people, they were sent to capture vipers, and that aircraft were coming in the morning to gas Eden, killing everyone left by then.
Nicky and Vera use flares and propane tanks to ignite the greenhouse, causing an explosion.
Burton is arrested, as Cal recorded his walkie talkie conversation with Vera admitting his plan to kill everyone.
