Flawless (2007)

Watch Flawless: London, 1960. Laura Quinn is the lone female executive at London Diamond Corporation. She is frustrated as her talents are rarely acknowledged and her less-experienced male co-workers are promoted ahead of her. She is shocked, but intrigued, when the mild-mannered night janitor, Mr. Hobbs, approaches her with a daring but simple plan to steal a handful of diamonds from the vault. Laura agrees to help, but she is soon in over her head. And it is not long before insurance investigator Mr. Finch has his eyes on her.
