Plot synopsis: David Cassidy: Man Undercover was an American police drama starring David Cassidy, four years after his run starring in the The Partridge Family. The series was spun off after Cassidy guest starred in a special two-hour episode of another show, Police Story, titled A Chance to Live, which aired in May 1978; this episode is therefore sometimes confusingly referred to as the pilot for Man Undercover. In A Chance to Live, Cassidy portrayed undercover police officer Dan Shay, a cop who successfully infiltrates a high-school drug ring as a fellow student. Cassidy earned an Emmy Award nomination for Best Dramatic Actor for the role. He reprised the role of Officer Shay for the Man Undercover series, which aired on NBC from November 2, 1978 to July 12, 1979. Only ten episodes of the show aired prior to its cancellation.
