Luther Heggs (Don Knotts) is a typesetter at a newspaper who longs for a chance to be a reporter. Editor Beckett (Dick Sargent) gives Luther his big break and assigns him to spend the night in a house generally considered to be haunted. The situation allows a broad canvas for Knotts to react to sight gags with the special brand of eye-popping nervousness that made him a star. Former Playboy Bunny Joan Staley plays the pretty girlfriend of star reporter Ollie Skip Homeier.
Roy Fleming (Don Knotts) is signed on to the space program at NASA by his father Buck (Arthur O'Connell), a gung-ho former World War I vet who is trying to make something out of his son. Roy becomes a janitor who is afraid of heights and mistaken for an astronaut through a series of comedic mishaps. (Jesse White) plays Roy's boss Donelli, with (Leslie Nielsen) as space hero Major Gifford. Knotts uses his patented brand of nervousness to perfection in this lighthearted situation comedy.
