Fernando (Fernando Tejero) is a loser. A gray type, without ambition, that works like bookcases distributor in a supermarket of the quarter. In his free short whiles, he is a substitute keeper of a football team, a third regional one. In all the season he has not played a single minute. But the last Sunday of the league the referee indicates penalty and the regular keeper injures itself. Fernando must occupy the goal for the first time. If penalty scores, the team of the district will proclaim champion. If no, all the effort of a year will not have been worth for anything. When the penalty is just about to be kicked, a group of indignant fans with the referee invades the field and prevents the kick. The competition committee decides that the penalty must play the following Sunday, in the same goal, with same players and the field closed to the public. El Penalti más largo del mundo, (The Longest Penalty Shot in the World) is exactly the history of that week of delay.

Leo, an orphaned mute girl who can't fit in, escapes from the shelter where she lives in order to go to a fishing competition that reminds her of her parents. On the way, Lou, a non-conformist with no job or benefit, finds her hitchhiking and, without knowing Leo's real purpose, agrees to take her in his car, thinking he is taking her back home. Together they will embark on an adventure in which, despite the obstacles they encounter along the way, they will become inseparable and discover the extraordinary meaning of the word family.
