Stu Bailey and Jeff Spencer are the wisecracking, womanizing private-detective heroes of this Warner Brothers drama. They work out of an office located at 77 Sunset Strip in Los Angeles, California, right next door to a snazzy restaurant where Kookie works as a valet.

Hale also join the firm, and Suzanne is their leggy secretary.

The show was a milder version of a successful 1973–74 ABC series, Toma, starring Tony Musante as chameleon-like, real-life New Jersey police officer David Toma. While popular, Toma received intense criticism at the time for its realistic and frequent depiction of police and criminal violence. When Musante left the series after a single season, the concept was retooled as Baretta, with Robert Blake in the title role.
