Júlia, a purposeful and conservative student gets a scholarship in Paris in the beginning of the 1990s. She rents a tiny flat on the top floor of an elegant building. The only way to the flat leads up a dim back staircase. She has to share the toilet with a repulsive and mysterious stranger. This common toilet becomes the setting of their battles. Júlia is repulsed and attracted at the same time by the autonomous musician, getting further and further away from the world of her home and her love. In the flat, she manically tries to cover up everything that is dirty, stained and stinking, and the same way, she tries to smother the dirty thoughts in her mind too - but there comes a point when she can no longer avoid facing herself.
