Jimmy Dorr is sent to Trinidad to assassinate an aging gangster by the name of Konno. At the end of the first act we learn that Jimmy was sent into a trap and that he's actually been brought to Trinidad in order that he himself be assassinated. Slate, with Sailor as a hostage, is put into a vault room with Jimmy. Slate is given a gun, a single bullet, and instructions to murder Jimmy or he himself will be murdered. By means of a clever ruse, Slate emerges unscathed and takes Sailor home.
