Magnum (Tom Selleck) is asked by Deputy DA Carol Baldwin (Kathleen Lloyd) to help locate her 17-year-old cousin Becky (Linda Grovenor). The one person who may know the girl's whereabouts is her former boyfriend Darryl (Asher Brauner), who is now serving time on a prison farm. In order to pry the necessary information from Darryl, Magnum goes undercover as a hardened convict--with the expected violent results. Ironically, this final episode of Magnum, P.I's fifth season was cowritten by real-life "private eye to the stars" Anthony Pellicano, who later wound up behind bars himself on a variety of charges!
