The plot follows the story of twin brothers — one a coldhearted violent police officer, the other a helpless romantic with a mental disability.

The film was adapted from the novel Canciones de Amor en Lolita's Club written by Juan Marsé.

[2] Raúl Fuentes, a brooding police officer prone to violence and alcohol, is placed on unpaid leave after he has beaten Moncho Tristán, the son of a local drug trafficker.

He would give him some documents that prove the involvement of the Tristán family in drug trafficking and prostitution if Raúl agrees to reveal the story only after Mazuera has left the country.

When Raúl finds out that his brother is working in a nightclub and has fallen in love with one of the prostitutes, he gets very upset and goes in search of Valentín at the bordello, called Lolita's Club.

The beautiful Milena is an immigrant from Colombia, who has left behind her daughter under the care of her mother and works to provide them with a better life, sending them money frequently.

The scheme unfolds accordingly, with Valentin storming out of the club after he catches his brother engaged in sexual activity with Milena.

At that moment, two hit men sent by the mafia pull up to the car and, mistaking Valentín for his brother, shoot and kill him.
