Here again, staring at the mirror, here again with same idea of taking his own life. In his clenched fist, Mum's sleeping pills, the only hope of escaping the hell his school mates make for him; his only reason to live the love he has for his little sister Teresa. Years of bullying at school have reduced Santiago to a shadow of himself. But the arrival of new girl Lucía, unusual and strange, will rescue him from the cold inhospitable universe he inhabits and reawaken his hopes of smiling again. At school though, the bullying continues, and Nacho, the leader, will never stop in his mission to destroy Santiago one way or another. So Santiago, determined not to be defeated, will end up becoming what he most hates.
