At a party thrown by a sporting club, Raffles and Bunny meet Barney MacGuire, an ill-mannered boxing champion from America. MacGuire not only shows off his extravagant boxing trophies to them, but also boasts that he has a secret trap guaranteed to catch any thief who tries to steal them. Raffles takes the boast as a challenge, and decides to make the attempt alone. However, in the middle of the night of Raffles's burglary attempt, Bunny receives a cryptic telephone call from Raffles, telling Bunny that he has been caught.
