A year ago, Ricardo and Felipe, in charge of taking the children to a camp, stayed outside the train leaving the children inside. Clara no longer trusts them and this year she decides to take the children personally with the help of her friend Susana. However, now they will be the ones who, as a result of an accident, are separated from the children.

When Ricardo, a responsible father, decides to personally take his son to a camp in Asturias, other parents propose that he should also take care of their children. When the train is about to leave, Felipe, a flamboyant individual and grandfather of two of the children, shows up at the station.
