Diego has just been voted best young player in Europe and at the age of 20 he is on his way to making his team, Atlético de Madrid, champions of La Liga. But his impulsive and conflictive character makes the club, fed up with his excesses, hire Álex, a withdrawn and lonely psychology professor, to improve his behaviour. The two will have no choice but to learn to understand each other.

Set in 1978, the film marks the fourth joint effort between Monzón and Jorge Guerricaechevarría, and tells the action-packed, adrenaline-fuelled story of 17-year-old Nacho Cañas, an introverted student who lives in Girona and who is something of a misfit. When he meets El Zarco and Tere, young delinquents from the city’s Chinatown district, he gets caught up in a love triangle that leads him to indulge in an unrelenting onslaught of thievery, burglary and hold-ups that will change his life forever. The film is the chronicle of the summer during which Nacho experienced his first love and came of age, constantly crossing the boundary between two worlds, and overstepping the line that exists between right and wrong, between justice and injustice.
