Eve Gill (Jane Wyman), an aspiring young actress, shelters a fellow acting student, Jonathan Cooper (Richard Todd), from the police. He is suspected of murdering the husband of his mistress, Charlotte Inwood (Marlene Dietrich), a famous singer. Jonathan claims that he became implicated when he tried to help Charlotte destroy the evidence. Eve's eccentric father, Commodore Gill (Alastair Sim), agrees to hide Jonathan in his house while she proves his innocence. To do this, Eve becomes Charlotte's temporary maid. Eve's Father devises a plan to force Charlotte to confess in front of the inspector investigating the case, Wilfred Smith (Michael Wilding). When the plan doesn't work, Eve tries blackmailing Charlotte into a confession while the police listen outside her dressing room. Charlotte agrees to pay, but insists that Jonathan is the real killer.
