Film Dope

Drake is tasked with escorting two killers-for-hire to justice. Unfortunately things are complicated when the killers break loose and cause the plane to crash on an isolated island.

A very Avengers-like episode (no surprise since Brian Clemens co-wrote the screenplay), with a morbid humor overlaying the suspense. Cuthbertson and Stephens make an excellent Tweedledum-Tweedledee pair of killers, and Ripper gets to chew the scenery as a mad hermit, but Firbank's spoiled rich girl character (whose stupidity allows the killers to get loose) is annoying enough one rather wishes the killers would practice on her.
