Steve Austin has been assigned to train America's first female astronaut Major Kelly Wood. On her maiden-flight, a sudden explosion damages the Athena 1 and injures Kelly's co-pilot Osterman. Austin heads the rescue-team and follows her up to Skylab, only to find his bionic replacements malfunctioning in outer space.

A mercenary-for-hire plans to assassinate several world leaders at a summit using a high powered laser beam that will bounce off a satellite unless Col. Steve Austin can infiltrate his base and stop the mastermind before he sets his plan into motion. Of course it involves a bit of a challenge: Steve has to be fired onto the villain's island lair inside a torpedo casing, climb a dangerous precipice, vault a 30-foot high electrified fence and break into a secure compound.
