Julián is a graphic modeller for a video game company. In his social life, he is painfully shy, living in a fair-sized apartment, working from home as often as possible. One day, he ends up saving a young boy in the next apartment from a fire, and that action haunts him in ways that are not acceptable to society. Soon after, he meets Diana but even as this romance blossoms, the previous event is shadowing him to rear its ugly head and upend his life.
