Robocroc

When a top-secret unmanned spacecraft disintegrates on re-entry, its mysterious military payload crash lands in the crocodile habitat of a place called Adventure Land, a combination water park, amusement park and world-famous crocodile exhibit. Following its pre-programmed instructions, the payload – a next-generation nanotech-based combat drone – finds a host in the form of the park’s prize twenty-foot Australian saltwater crocodile, Stella. She is the largest saltwater crocodile in captivity. Immediately upon infecting its host, the drone payload’s nanobots begin to transform Stella from an organic, living creature into a lethal killing machine with only a single directive: survival! Before chief zoo-keeper Duffy and reptile biologist Jane are able to figure out what’s going on, they find the park taken over by the government team responsible for the secret project. As the crocodile continues to transform, it escapes the crocodile exhibit and enters the water park, running amok, killing dozens of patrons. But that’s just the beginning. The crocodile, now programmed to kill, will target anything and anyone for its next meal.
