Jack Lemmon and Robert Mitchum star as Tony and Felix, co-owners of a tramp-steamer service in the West Indies. Threatening their friendship is itinerant trollop Irena (Rita Hayworth). Tony seethes with jealousy as Irena gravitates towards Felix, leading to a heated confrontation. Felix retaliates by blowing the whistle on Tony's under-the-counter smuggling activities. Tony in turns plots to kill his former partner, but changes his mind when Felix saves his life during a shipwreck. The supporting cast includes Herbert Lom, Bernard Lee, and Anthony Newley. ~ Hal Erickson, Rovi
