Toñi, Carlos and their three children are having the worst summer of their lives, no vacations, locked in a 50-square-meter apartment, both parents working full-time... and to top it all off, the air conditioning breaks down in the middle of a heat wave. Toñi and the children convince Carlos to stay overnight in the empty mansion where he has been assigned to work as a gardener for a couple of weeks. What was supposed to be a one-off escape from the summer heat turns into an unforgettable vacation full of adventures, among mansions and famous neighbors, which will transform this family forever and make them rethink what is truly important to each of them.
