On the run from the authorities, the dashing Angel O'Reilly (Dorothy Lamour) finds herself lost and cash-strapped in Mexico, reluctantly accompanied by the shady Boris Cassall (George Rigaud). Soon, she lands a job as a nightclub singer after duping a club owner into believing she's a Spanish countess. One night, honest banker Tom Grant (Patric Knowles) stumbles into the temptress' show with his estranged wife Helen (Ann Dvorak), toting Manolo, a Mexican bullfighter, on her arm. Tom loves Helen. Helen loves Manolo. Manolo loves Angel - and so does Boris. Meanwhile, Angel increasingly finds herself drawn to Tom.
