The Bribe (1949)

In pursuit of stolen aircraft engines on Carlotta, a Central American island, federal agent Rigby meets chief suspect Hintten and his wife Elizabeth, a sultry cafe singer. He is watched by Bealer, a "pie-shaped man" with sore feet. Rigby knows he's on the right track when Bealer offers him money to leave Carlotta. When Rigby and Elizabeth are drawn to each other, the gang realizes there's more than one kind of bribe. Everybody sweats.
