The main character, Ruben Brandt, suffers from agonizing nightmares featuring images from famous paintings in museum collections around the world: the Louvre, the Hermitage, the Museum of Modern Art in New York, and the Tate Gallery. He believes that the only way to cure himself is to steal 13 artistic masterpieces from the most secure museums in the world.
The film is filled with elements of thriller, psychedelia, and surrealism, as well as numerous references to works of visual art by artists of the 19th and 20th centuries. The very name of the protagonist directly refers viewers to the names of two outstanding 17th-century artists: Peter Paul Rubens and Rembrandt.
