The Sweeney: Down to You, Brother

Regan encounters a former nemesis at a party, who drunkenly admits involvement in an earlier robbery in which he was let go due to lack of evidence. He disapproves of his daughter's villainous boyfriend, and Regan suspects he is being exploited to help break the romantic union. However, an even darker plan is being hatched, with the daughter an innocent pawn in a robbery. Kenny Lynch and Derek Francis guest star, with John Thaw and Dennis Waterman
