Frank investigates a body of a struggling comedian found at the bottom of a cliff in a car crash.

In order to catch the person responsible, Frank takes the place of the deceased at the nightclub he worked.
After four episodes had aired the show was cancelled, Tony Thomopoulos, then president of ABC, later explained that the show was cancelled because "the viewer had to watch it in order to appreciate it". Two more episodes had already been made, but remained unaired. The other four episodes gained a strong cult following through repeats on TV, which led to the 1988 movie version The Naked Gun: From The Files of Police Squad! and its sequels. All six episodes were released on a DVD keepcase in 2006.
