Salva and Mía, fans of the Beatles and B-movie horror films, have an unusual hobby: conquering abandoned houses. Sneaking into buildings in ruins, they peer out of the windows and ponder on how life must have been there. One night, their game takes an unexpected turn. On a ledge of one of the houses they find a box. And the box contains a dead person's ashes. Suddenly, they are hit by endless questions. Who was this man? Why was he there? What does it have to do with them? The problem is that there isn't much time for Salva to get the answers to these questions that she needs, nor to discover her true feelings towards Mía.
