At a Thai hospital, a doctor and his seven nubile nurses engage in the sale of dead bodies. Jealousy causes one of the nurses to threaten to blow the whistle on the practice, so the others murder her. Soon the spirit of the slain nurse seeks revenge. In flashbacks we see the events leading up to the murder, and realize the full range of relationships between the main characters.

Sutin, a teenage rock musician, masturbates gleefully, and often. Way too often. One night, flying sperm escape and impregnate local women. The babies grow into an army of little creatures with the teen's head -- and libido. Not only do the nasty little monsters think only of chicks and jerking off, they also have a distressing tendency to die at the moment of ejaculation. The city really starts to panic when aliens accidentally turn one of the spawn into a giant.
