Loud music. Pornography. Burning stuff to the ground. These are a few of Hesher's favorite things. And they are what Hesher brings into the lives of TJ and his father, Paul, when he takes up residence in their garage uninvited. Grief stricken by the loss of TJ's mother in a car accident, Paul can't muster the strength to evict the 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.
