Marlene Dietrich and Gary Cooper star in this comedic drama about a crime spree that leads to love. In the most elaborate jewel heist in European history, the beautiful and conniving "Countess" Madeline (Dietrich) embezzles a small fortune in pearls. As she makes her getaway to Spain to deliver the hot goods, her escape is thwarted by car trouble, until a handsome and likeable young tourist (Cooper) helps her out. She shows her gratitude by leaving the unsuspecting good Samaritan in the dust - literally! But when he accidentally ends up with the pearls, she must feign romantic interest to get them back. The charade soon turns into the real thing however; and Madeline realises that her only hope of happiness is to clean up her act – no matter what the cost – or lose the man she loves.
