Now, frustrated and broke, his Uncle Sal appears with an offer. Gavins father has sold the family business. To get his share of the proceeds,Gavin must return home for his fathers birthday party. Swayed by the money, he sets off north and picks up a hitchicker with a secret. Their journey is difficult but ultimately rewarding.
