In the year 2000, twenty-somethings Pepo, Roge, Costa and Juan Luis undertook the dream trip: the Interraíl. But on their first stop in Paris, the adventure, and their friendship, ended abruptly. Twenty years later Juan Luis has passed away and, as a last will, he has decided to donate his juicy inheritance to his three old friends. But in return he asks them to do the Interrail that they could not do with fun conditions ... they have to take the ashes of his friend with them so that he can "live" the experience with them. Out of “love” for Juan Luis, these three 40-year-old adolescents will have to resolve their differences, visit the same cities and experience the same revelries, but in a much more pathetic way. And with cholesterol through the roof.
