See How They Run

In 1953 London, Agatha Christie's play The Mousetrap celebrates its 100th performance, and sleazy American director Leo Köpernick has been hired by producer John Woolf to direct the film adaptation. After Köpernick's drunken behaviour towards the female lead Sheila Sim leads to a fistfight with her husband and co-star Richard Attenborough, Köpernick is killed backstage by an unseen assailant.
