Fourth passenger

In order to solve the economic problems, Julian (Alberto San Juan) chose to become a carpool driver through mobile phone software.During this process, he often received orders from passenger Lorena (Blanca Suárez), and the two gradually established deep feelings on the way to and from Bilbao and Madrid.Despite the large age difference, they talked about everything on the road, and Julian gradually developed a good impression of Lorena.However, when Julian decided to confess to Lorena on the road of carpooling, the plan was broken by the arrival of two other passengers.The two passengers are Rodri Song, a bragging business chatterbox, and Carlos, a hippie boy who loves to travel with music.In a series of events, including supermarket fights, highway car accidents, night stays in the bath center, etc., Julian gradually felt that he might not know Lorena, and Lorena's interaction with other carpooling men also made him angry.During a large traffic jam on the highway, Julian decided to chase him back and face Lorena bravely.Despite encountering many difficulties and accidents in a series of farces, Julian finally mustered up the courage to confess to Lorena, and the two came together.
