Loud music. Pornography. Lighting fires. These are a few of Hesher’s favorite things. And they are what Hesher (Joseph Gordon- Levitt) brings into the lives of TJ (Devin Brochu) and his father Paul (Rainn Wilson) when he takes up residence in the garage uninvited. Grief stricken by the loss of TJ’s mother, Paul can’t muster the strength to evict the strange squatter and soon the long-haired, tattooed Hesher becomes a fixture in the household. Like a force of nature, Hesher’s anarchy shakes the family out of their grief and helps them embrace life once more.
