A down-on-her-luck San Francisco woman, turning in desperation to jewel robbery, barely escapes getting nabbed in a heist and moves to Los Angeles where she gets an honest job as a waitress. Her troubles start again, however, when she falls madly in love, blind to the fact that her boyfriend is a four-flushing, small-time con man.
Unfortunately the movie Once a Thief is not yet available on Paramount Plus.
