Walking home, Samantha Adams, a trainee nurse, is mugged by a gang of teenage hoodlums: Pest; Dennis; Jerome; Biggz; and leader Moses. Interrupted when a meteorite falls from the sky into a nearby car, Samantha escapes. As Moses searches the wreck of the car for valuables, his face is scratched by a small alien creature. The creature runs away, but the gang chase and kill it. Hoping to gain fame and fortune, they take the dead animal to their acquaintance, Cannabis dealer Ron.
