Hedy Lamarr in Dishonored Lady (1947)

Madeleine Damien is the fashion editor of a slick Manhattan magazine by day and a lively party girl by night. Unfortunately, the pressures of her job, including kowtowing to a hefty advertiser, and her bad luck with men are driving her to a breakdown. She seeks the help of a psychiatrist, and under his orders, quits her job and moves into a smaller flat under a new identity. She becomes interested in painting and a handsome neighbor. He soon finds out about her past when an ex-suitor implicates her in a murder. (Written by Daniel Bubbeo on imdb.)
