Follow the adventures of Steve Austin, cybernetically enhanced astronaut turned secret agent, employed by the OSI, under the command of Oscar Goldman and supervised by the scientist who created his cybernetics, Rudy Wells. Steve uses the superior strength and speed provided by his bionic arm and legs, and the enhanced vision provided by his artificial eye, to fight enemy agents, aliens, mad scientists, and a wide variety of other villains.

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 more resilient 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.
