Anthony Asquith's vivid and subtle courtroom drama stars David Niven as the eponymous officer desperate for money owed him by the army, and badgered by his neurotic wife Valerie. When WRAC officer Alison Graham goes to Niven's quarters to warn him about a plot to set him up, Carrington finds himself charged with misappropriating army funds, being absent without leave and improperly entertaining a WRAC in his room.
