Teresa gets her first taste of crime -- and its consequences -- when, during World War II, she is nabbed for robbing an apartment. But being poor and perpetually starving, the pretty petty thief doesn't give up her quest for ill-gotten gains and soon turns to pick-pocketing. Despite her questionable thieving skills, the bumbling crook tries scheme after scheme, pilfering from strangers and dodging the law as she searches for a way to fund an adequate meal.
