The Big Clock on IMDB
The story is told in flashback. When it begins, George Stroud (Ray Milland) is shown hiding from the police behind the "big clock" ― the largest and most sophisticated one ever built, which dominates the lobby of the giant publishing company where he works.
Stroud, a crime magazine's crusading editor who is eager to spend more time with his wife (Maureen O'Sullivan), plans a long-postponed vacation from his job. Instead of meeting his wife at the train station, however, Stroud is preoccupied by an offer by his boss. He begins drinking and spends the evening out on the town with a glamorous blonde. She is later murdered and Stroud is assigned by his Hearst-like publishing boss Janoth (Charles Laughton) to find the killer.
While investigating, Stroud tries to keep the facts of his night with the woman a secret because witnesses could recognize him. As the investigation proceeds to its conclusion, Stroud must try to disrupt his ordinarily brilliant investigative team as they increasingly build evidence (albeit wrong) that he is the killer.
