Private detective and former football player Harry Moseby gets hired on to what seems a standard missing person case, as a former Hollywood actress whose only major roles came thanks to being married to a studio mogul wants Moseby to find and return her daughter. Harry travels to Florida to find her, but he begins to see a connection between the runaway girl, the world of Hollywood stuntmen, and a suspicious mechanic when an unsolved murder comes to light.

Columbo is a friendly, verbose, disheveled-looking police detective who is consistently underestimated by his suspects. Despite his unprepossessing appearance and apparent absentmindedness, he shrewdly solves all of his cases and secures all evidence needed for indictment. His formidable eye for detail and meticulously dedicated approach often become clear to the killer only late in the storyline.
