Àlex, Carles and Jordi have not seen each other for some time, the lockdown and the entrance to the university have cooled their relationship. When summer arrives, Àlex suggests to both friends to go to the beach they used to frequent during their high school years. Carles agrees while Jordi prefers not to go. When they arrive at the supposed beach, they realize that they are actually in an abandoned station. They decide to investigate the place and wait for the next train to take them to the beach.
