Steve Austin and Jaime Sommers, the iconic heroes of The Six Million Dollar Man and The Bionic Woman, are together again... and at each other's throats! The FBI recruits Austin to investigate a rash of brutal murders, and the Bionic Man discovers that those slain were all accident survivors whose limbs and organs were replaced by cybernetics. Enter Trench, a serial killer whose very life depends on butchering victims and harvesting their bionic parts! Soon after, Austin disappears, and only his former lover Jaime Sommers - herself a cyborg with uncanny abilities - has any hope of tracking him down. When their paths cross, will their tragic past and different tactics towards Trench's defeat pit them against one another?
