The mutant victims of a terrible plague that almost wiped out Earth's population are exiled to outer space aboard a ramshackle ship. They have no hope of returning home, until an ambassador from Earth ("Desperate Housewives'" James Denton) arrives and offers them a desperate pact.

In the not too distant future, Watchbird robots, previously used as unmanned weapons for the military, are assigned to aid police forces in a small number of test cities. Their task is to prevent killing before it happens. However, soon everyone discovers the fragile formula of life and death.
