Help is needed for Dominique Deschamps, the lovely woman who lost her wallet after flirting with Scotland Yard "loan" detective Eddie Arlette. When Eddie Arlette discovers the wallet he ultimately finds Dominique Deschamps, but is ambushed by Paul and Jean Fortier. Eddie gets knocked out, but not after the lovely lady hands him a book of matches asking for help. Monty Pippin and Eddie Arlette start an investigation, which leads them to a man named Anton Levy. Dominique and Anton were passionate about each other, but Dominique turned Anton into the French police. Anton's would agree to going to prison, but first he wanted to go to London before prison, so he could tie up some loose ends. Eddie and Monty Pippin think he's come to London to kill Dominique. Eddie, Monty, and the Scotland Yard tactical team head into Anton's mansion, where he and a very much alive Dominique greet them. Nothing bad going on here. Eddie is left scratching his head...until Michel Hoffman. Michel is Dominique's true love, not Anton. Eddie heads to Anton's mansion to get Dominique, but Michel is already there, saving her. Anton says the two will expire if Anton's true love is not given to him. Eddie finds Dominique, who refuses to go back. The hit man Jacques Desmarais is already out for Dominique. Eddie goes back to Anton's house to reason with him, but there he realizes that the love of Anton's life is his young daughter Isabelle, who joins Anton for his last meal before his imprisonment.
