When ex-convict cabbie Jimmy Carmody is framed in a jewelry store robbery and murder, an old friend arranges for him to flee the country to the island of Caribo, where a person’s past doesn’t matter. Once there, he is approached by his pal Rocky Crane and invited to join their gun-smuggling operation to assist forces that want to overthrow the local military dictatorship under Colonel Gomez. Though Carmody refuses, his new job at a hotel where Crane’s aide (and his girlfriend’s brother) lives involves him deeper in the revolution plot.
