Don't mess with nature, especially when you're making what sets out to be a horror thriller.

The foolish scientists in this number are working on a special aggression-increasing drug and accidentally let loose a cobra called Seth who's been injected with it.

Seth is one nasty critter and he's coming our way.

It's passable horror for most of the way, but you won't care much for the characters.

Co-director Scott Hillenbrand stars as Dr Kagen. The OK special effects are by the Chiodo Brothers, who previously created creatures for Teenage Mutant Ninja Turtles and Killer Klowns from Outer Space.
