Alberto San Juan (The Other Side of the Bed), Blanca Suárez (The Bar), Ernesto Alterio (Perfect Strangers), and Rubén Cortada (The Prince) come together in this hilarious and wild road movie directed by Álex de la Iglesia.

San Juan plays Julián, a 50-year-old divorcé who regularly shares his car with strangers—though one of them is no longer a stranger. Lorena, a young woman who often travels to Madrid, has become a regular passenger in his car and, lately, in his heart as well. Julián plans to use this trip to confess his feelings for her, but a mistake in choosing the other passengers leads to the inclusion of the most unbearable person in the world, setting the journey on an unexpectedly chaotic path.

Written by De la Iglesia and his frequent collaborator Jorge Guerricaechevarría, *The Fourth Passenger* is a romantic dark comedy brimming with unexpected twists, action, fast-paced humor, and romance, all infused with the distinctive style of its director.
