Scientist hold talking, super-intelligent babies captive, but things take a turn for the worse when a mix-up occurs between a baby genius and its twin.

SIRIUS 6B, Year 2078. On a distant mining planet ravaged by a decade of war, scientists have created the perfect weapon: a blade-wielding, self-replicating race of killing devices known as Screamers designed for one purpose only -- to hunt down and destroy all enemy life forms.

Josh meets a young woman who shortly afterwards collapses and is rushed to hospital in an ambulance. He follows after her only to find that there is no record her being admitted, and he soon learns that her roommate also vanished after being picked up by the same ambulance. Convinced of a conspiracy, Josh proceeds to investigate, despite the discouragement of the police.
