A detective investigating the death of a heroin-addicted prostitute uncovers evidence pointing to the existence of a murderous devil cult.

Sailor meets singer in Cuba. He's due to ship out, but hits it off with her, so he sticks around. Trouble brewing on many fronts - singer's best friend doesn't like the sailor, and singer has another suitor anyway. Rich guy takes her to all the fancy Cuban sports events - jai-alai, horse racing. Much more glamorous than spending time with Sailor. Can he win her over before he gets in trouble for letting his ship sail without him?
