This time, undercover cop Tony Baretta (Robert Blake) is on the trail of a professional arsonist. In hopes of expediting his assignment, Baretta enlists the aid of a retired pyrotechnics expert -- who, after sustaining serious injuries in a tenement fire, may turn out to be too unstable to be of any help. Series star Blake is afforded the opportunity to ad-lib to his heart's content in this episode.
