A private detective solves cases in Los Angeles.

An insurance company hires Cannon to investigate the plane-crash death of a country-and-western singer.

Cannon is called in when a gubernatorial candidate wants to avoid police involvement in rescuing his kidnapped son.

The trail of suspects in an armored-car robbery leads Cannon to a hamlet where he receives an unfriendly greeting.

The death of a private-investigator friend during a missing-persons case leads Cannon to join the probe.
