Colt Seavers is a stuntman, who when he is in a financial crunch, works as a bounty hunter. He is aided by his cousin Howie, who has gone to practically every college and studied every course for a semester, and his protoge Jody. He also helps friends who are framed or being threatened by criminals. He was working for Samantha Jack in the first season, the next season, Terri Michaels became Colt's new boss; she would be there for three seasons, the last season Colt got his jobs either from Pearl Sperling or Edmund Trench.

The theme song, "The Unknown Stuntman", was sung by series star Lee Majors, and actually became a minor hit in the early 1980s. The lyrics of the theme song include the line, "I've been seen with Farrah," a reference to Lee Majors' ex-wife, Farrah Fawcett.

Colt Seavers:
This is the story of one of America's great unsung heroes. I mean you've seen him but you never knew who he was. You've cheered for him and cried for him and women have wanted to die for him. But did he ever get any credit or the girl? No! He's what we call the "Stuntman" and the reason I'm talking so fondly about him is, well because it's me, Colt Seaver. Anyway, picture work isn't wall-to-wall employment so maybe you wonder how a guy keeps his head together? Well, one way is to wait by the phone and wait and wait. The other is to take an occasional job with the court system of the United States of America where a man is considered innocent until proven guilty. Unfortunately sometimes a lot of these people get out of jail on what we call bail and they'd run like hell! ...and that's where I come in. I sometimes pick up rent money trying to find them and bring them back to justice
