Penelope (1966)

"The world’s most beautiful bank-robber"

When Penelope gets married to banker James Elcott, she finds him too preoccupied with work to pay much attention to her, so she robs his bank in disguise. After she confesses to her psychiatrist, Greg Mannix, he offers to return the money for her, as he is secretly in love with her. However, he abandons the money when the police approach. Penelope becomes determined to admit to the crime, but neither James nor the police believe her story.
