When Grace Kelly retires from movies to marry Rainier III, Prince of Monaco, Sir Alfred Hitchcock (Toby Jones) looks for a similar blonde and finds her in a television model. The little known Tippi Hedren (Sienna Miller), who will star in his movie adaptation of horror story "The Birds". Hitchcock is obsessed with Tippi sexually, and when she rebuffs his advances, sadistically puts her through five days of filming where she is attacked and injured by real birds. Hitchcock's wife Alma (Imelda Staunton) and his assistant Peggy Robertson (Dame Penelope Wilton) are appalled, but can do nothing. Tippi is resolved that she will not give in to Hitchcock despite the situation giving her nightmares. Hitchcock and Tippi make a second movie, Marnie (1964). Having admitted that Alma is the only woman with whom he has ever had sex, and that he now finds her cold, Hitchcock continues to pursue Tippi, bombarding her with phone calls declaring his love for her, yet reminding her that he alone made her famous and she owes him. At this stage, Tippi demands that her contract be terminated and they never worked together again.
