Bella is persuaded that she is hearing noises, unaware that Paul enters the upper floors from the house next door. When Bella comments on the lights' dimming, he tells her that she is imagining things. Paul lights the gas lamps to search the closed-off upper floors, which causes the rest of the lamps in the house to dim slightly. Rough ( Frank Pettingell), a former detective involved in the original murder investigation, begins to suspect him of Alice Barlow's murder. Bella ( Diana Wynyard) soon finds herself misplacing small objects and, before long, Paul ( Anton Walbrook) has her believing she is losing her sanity. The house remains empty for many years, until newlyweds Paul and Bella Mallen move in. In Pimlico, London, Alice Barlow ( Marie Wright) is murdered by an unknown man, who then ransacks her house, ripping her furniture apart as if desperately searching for something.


The play had been performed on Broadway as Angel Street, so when the MGM remake was released in the United States, it was given the same title as the American production. The film adheres more closely to the original play upon which it is based – Patrick Hamilton's Gas Light (1938) – than does the 1944 MGM remake. Gaslight (released in the United States as Angel Street) is a 1940 British psychological thriller film directed by Thorold Dickinson which stars Anton Walbrook and Diana Wynyard, and features Frank Pettingell.
