After the Korean War, Americans Tony and Felix own a tramp boat, the Ruby, which they use for small-scale smuggling around the Caribbean, along with a third crewman, Jimmy Jean. One day, their bartender contact, Miguel, introduces them to an American businessman who has been enjoying the company of beautiful but passport-less European goddess Irena. He has to return to Detroit, but wants to arrange for her to get to another island. They are reluctant, but $1,200 proves very tempting. On the voyage, Tony starts falling in love with her. Knowing the kind of woman she is, Felix does his best to protect his partner by warning Irena to stay away from Tony. However, Felix starts falling for her himself. When she disembarks, Tony goes with her, ending his partnership with Felix. Tony and Jimmy Jean take on a shady job, but are intercepted by the authorities. They have to abandon ship and swim to a nearby island to avoid arrest. Tony takes a job on a cargo ship to get back to Irena. He also plans to kill Felix, correctly suspecting that his former partner tipped off the customs agents to get rid of the competition for Irena. However, while Tony is away, she goes to Felix and confesses she loves him. After a collision, Tony is trapped below deck under a girder with time running out; the ship is aflame and carrying a highly explosive cargo. Doctor Sam Blake offers the only way out, by amputating Tony's trapped legs, but he would rather die. Felix goes aboard and stays with him. An explosion frees Tony from the wreckage, and Felix carries him to safety. After Tony has recovered, he confronts Felix and Irena in a bar. It is there he realises that Irena loves Felix and not him, leaving him to walk away and cut his losses by saying, "some days you win, some days you lose".
The film was Rita Hayworth's return to motion pictures after a four-year absence. The producer and part owner of the production company Warwick Films, Albert R. Broccoli, later to become famous as the producer of the first 16 Eon made James Bond films, makes a cameo appearance in the film as a drug smuggler.
The film needed to make $5,500,000 to break even and by October 1957 was going to come in $750,000 short. This financial failure caused Warwick Films to scale back its production.
