Mr. Bean (ROWAN ATKINSON) wins a church raffle for a vacation in the South of France. He is determined to enjoy and remember his adventure, away from the perpetual rain of London, and so he brings along a digital video camera, which he uses to tape everything. His adventures are extremely episodic.
In Paris, he eats in a fancy restaurant and gets on a train, where he meets a young boy, Stepan (MAX BALDRY), whose father Emil (KAREL RODEN) is a famous film director. They're all on their way to Cannes, but dad misses the train (owing to inadvertent shenanigans by Bean) and Bean takes it upon himself to look after the boy.
When they are briefly separated, Bean meets Sabine (EMMA de CAUNES), a young actress who hopes to make her international debut in a film at the Festival. They rediscover Stepan at a truck stop (he has been traveling with a van full of very nice and shaggy musicians), then make their way to Cannes, where Stepan hopes to catch up with his father.
More hijinks at the Festival include Sabine realizing that her director, Carson Clay (WILLEM DAFOE) has cut her scene from his film, so it can focus on him, and only him. To help her, Bean hooks up his video camera to the projector and shows the audience beautiful, candid shots of Sabine. Stepan finds Emil, Sabine is a star, Carson accepts the changes in his film, and Bean finally makes it to the beach.
