Joe Mannix and Peggy go to a nightclub intending to listen to a young guitarist, where Peggy recognizes a fugitive criminal named Brastow. Joe manages to recapture Brastow, who is to be extradited to New York to face charges of murdering a police officer. Brastow is to be escorted by an old acquaintance of Joe's named Ross Santini, now a New York detective. But Joe becomes puzzled by several attempts on his life by men he believes to be working for Brastow, and concerned about his friend Santini's increasingly odd behavior.
