Mr. Bean, played by Rowan Atkinson, participates in a raffle, but to his dismay, his number 616 is mistakenly read upside down as 919. This confusion frightens him, leading him to toss his ticket into a toy train cart. In a twist of fate, he retrieves his ticket just in time to claim an exciting grand prize: a train journey to Cannes, a Sony video camera, and EUR200. Enthusiastically, Mr. Bean begins filming his adventures with the new camera.
Upon arriving at Gare Du Nord in Paris, a misunderstanding with a taxi forces him to walk to Gare de Lyon to catch his next train to Cannes. With an hour to spare before departure, he delights in the opportunity to try French seafood at the lavish Le Train Bleu restaurant. However, his lack of French leads him to accidentally order a plate of oysters and Langoustine, which he struggles to eat. In a rather comical mishap, he discreetly dumps the oysters into a lady's handbag, much to her shock when her phone rings, while he devours the whole Langoustine, shell included.
Back on the platform, Mr. Bean encounters a Cannes Film Festival jury member and Russian critic, Emil Dachevsky, who helps him film his dramatic entrance onto the train. Although Mr. Bean hops aboard just in time, Dachevsky is left behind, causing a series of misadventures. During their frantic attempts to reunite, Mr. Bean accidentally loses his bag, leaving behind his ticket and passport filled with cash.
While trying to make ends meet, Bean performs a mime show to the beautiful tune of Puccini's "O Mio Babbino Caro," which surprisingly attracts a crowd and allows him to buy a bus ticket to Cannes—until a breeze snatches it away, only for it to get lodged in a chicken's talon. In his pursuit of the ticket, Bean steals a bike, only to have it flattened by a tank. A comical series of escapades leads him to mistakenly crash a TV advertisement set, injuring director Carson Clay in the process.
Soon after, Bean gets a lift from actress Sabine, who he previously met during the mishap involving the advertisement. However, their journey is interrupted by a news report portraying Bean as a kidnapper, which complicates their entry into Cannes. To avoid capture, Stepan dresses as Sabine's daughter, while Mr. Bean hilariously disguises himself as her mother. They manage to sneak past security just in time for the film premiere.
The screening reveals Clay's self-indulgent movie, "Playback Time," which the audience finds painfully dull. Disheartened, Sabine tells Mr. Bean about her missing scene, prompting him to use his camera to showcase her past footage, perfectly aligning with the film's narrative. This unexpected intervention delights the audience, and Bean, Sabine, and Clay bask in the standing ovation. Clay’s initial frustration melts away as he embraces Mr. Bean in gratitude.
Following the chaotic premiere, Mr. Bean enjoys the beach with the other characters from the film. The finale features a lively miming of "La Mer" (Beyond the Sea) alongside a host of familiar faces. In a whimsical post-credits scene, Mr. Bean scrawls "FIN" in the sand with his toe, filming until his camera alerts him of low battery, just before the waves wash away his message.
