Joe Mannix must find the kidnapped daughter of a Palm Springs mobster.

A potential candidate for governor employs Interect to probe his background. He believes that if the detective agency can't find dirt on him, then his political opponents won't.

Mannix reluctantly agrees to pursue a divorce case -- the woman involved is an old flame of his. The detective ends up being framed for murder.

A young girl wants to `rent a detective' to prove her father, who is on Death Row, is innocent. Mannix takes the case in his own time and must solve it without Intertect's help.

Mannix's former girlfriend sees a man she met on vacation but he flees, so she asks Mannix to track him down. However, things take a turn when it turns out the man is an assassin.

A young woman hires Intertect to do a background check on her boyfriend. Mannix believes she is surrounded by shady characters who seek to drive her back into a mental hospital.
