Samantha Stephens is a pretty, typical American housewife who just happens to be a witch.

Colonel Steve Austin, astronaut and test pilot, is badly injured when he crashes while testing an experimental aircraft. A covert government agency (OSI) is willing to pay for special prosthetics to replace the eye, arm and both legs he lost in the crash. Highly advanced technology (Bionics) built into them will make him faster, stronger and better than normal. In return they want him to become a covert agent for the OSI. It will cost $6,000,000 to rebuild Steve Austin.
