Teenage brothers Hombre and Transformer spend their days locked up in their suburban Montreal bedroom, writing songs and dreaming of stardom. Hombre, the younger one, is quiet, contemplative, and talented, a poet in the making. His older brother Transformer is stubborn, domineering, and secretly struggling with mental health issues. Their sequestered world is broken open one summer when their mother hires Spit, a girl from the local guitar shop, to help the boys improve their modest skills. But these good intentions set off a chain reaction with tragic consequences. Set in the early 80s, in a local music scene brimming with post-punk ethos and a disdain for classic rock, Because is a wry and charming depiction of a sibling relationship founded on feverish angst, unspoken admiration, jealousy, and the pursuit of the greatest song they can write from their own room.
