Plot

Ricardo is the chosen parent to take all the kids to a camp by train. On a stop, Ricardo and grandpa Felipe take an outdoors smoke-break, and the train leaves, with the children but without the grown-ups, setting off a hilarious chase.

Ricardo and Felipe are in charge of leading a group of family children to a summer camp in Asturias. The train they're traveling on departs before schedule while they're on the platform and leaves the unsupervised children inside. Ricardo and Felipe start an against-the-clock eventful chase trying to get onto the train before it reaches destination while the cheeky children try to avoid the train paranoid ticket collector with cunning tricks.
