CBS airs the 14th episode of Filmation’s live-action Saturday morning science fiction series Ark II. 
Ark II moves into an area where unexploded bombs from an ancient war have been detected. Jonah safely detonates one of them with a remote electromagnetic device, leaving a huge crater in the landscape but harming no one. But there’s a witness to this explosion: a man in homemade armor, on horseback, raises his jousting lance and charges toward the Ark. All he collides with is the vehicle’s force field, but that only slows him down: he thinks he’s Don Quixote, and his sidekick, reluctantly playing the part of Sancho Panza, apologizes profusely to Jonah. The Ark continues in its search for another unexploded bomb, finding it at the heart of a nearby village. The slightest jolt could set it off – such as a jolt from a self-styled knight errant who’s convinced that Jonah is the Black Knight.
