Appointment in London is a 1952 drama about a bomber pilot in World War II nearing the end of his flying career. Tim Mason (Dirk Bogarde) is one of the most daring pilots in the Royal Air Force. Hoping to reach 90 missions, Mason is dismayed when he is grounded from flying. He becomes more dispirited when his absence begins to negatively affect his crew and their missions, particularly two of his best men, Brown (Bill Kerr) and Greeno (Bryan Forbes). Mason reaches a low point when Greeno's plane is shot down during a mission, and he is killed. As a new mission prepares to leave the base, a crew member is injured, and Mason decides to take his place and reach his 90th mission. His commanding officer, Logan (Ian Hunter), is enraged when he learns that Mason has disobeyed orders. When the mission begins badly, Mason begins to wonder if he made the right decision.
