When a top-secret unmanned spacecraft disintegrates on a re-entry, it crash-lands in the crocodile habitat of Adventure Land, a combination of a water park, amusement land and world-famaus crocodile exhibit. The payload, a next-generation nanotech-based combat drone, finds a host in the form of a park's prize twenty-foot Australian Saltwater crocodile, Stella - the largest saltwater croc in captivity. The drone's nanobots begin to transform Stella from an organic, living creature into a lethal killing machine with only one single directive: Survival. The crocodile, now programmed to kill, will target anything and anyone for its next meal.
