Tom Spicer has Fragile X Syndrome, a form of autism and harbours a dream to meet his hero which his brother and sister promise to make happen, with hopes of good times and bonding on a road trip across America. But Tom's disabilities, a dysfunctional family and heavy metal's labyrinthine backstage world threaten the mission at every turn.
