Adam Knight is a young man who, having tried several jobs, decides to set up an agency, 'Knight Errant '59', to solve other people's problems - whatever they may be. There's plenty of scope and, assisted by former reporter Liz and idealistic young writer Peter, the latter-day Sir Lancelot is kept busy with a variety of curious and exciting cases. The series had two titles, Knight Errant '59 and Knight Errant Limited of which only two episodes exist out of the 75 produced.

Down-on-their-luck racers Larry and Deke steal from a supermarket manager to buy a car that will help them advance their racing chances. Their escape does not go as planned when Larry's one-night stand, Mary, tags along for the ride.

A biker gang incites a reign of terror in a California coastal town that culminates in four teenage girls being raped. Vietnam veteran Billy Jack has had enough, however, and takes on the depraved bikers single-handedly. He rescues young Vicky Barrington from their clutches, but then has to contend with not only the thugs, but also the ineffectual and racist local lawmen, who have it out for the half-Native American Billy.
