Alexandra has been playing tennis for as long as she can remember. After years of training under the instructions of her father, Julio (a retired tennis player who intends to relive his victories through his daughter), she has become one of the most promising junior tennis players in the Spanish circuit. During one of the most important tournaments of the 1978 season, the increasing pressure from her father will exert on and off the court will begin to affect her mental health. With the arrival of adolescence and the questions it brings, Alex will realize that, perhaps, this is not her destiny.

After receiving it as part of her inheritance, Ana decides to move into her painter grandfather's house with her partner, Lucas. In one of the rooms, they find an unfinished triptych that will make them go deep into a paranoid artistic process.
