So original: a story about a Down Syndrome lad, Zak, who escapes his care home and latches onto a stranger, Tyler, who is on the run after setting fire to a hostile fisherman's crab pots. An unlikely friendship develops with Tyler agreeing to help Zak achieve his obsessive ambition to be a wrestler, the Peanut Butter Falcon. The nurse from the care home, sent to track him down, becomes part of the escapade and she and Tyler fall for each other. So..... adventure, shocks, chases, love and ultimately triumph.
