Grimshaw Slade is a homeless and depressed werewolf with no hope in sight. Archie Ringwald is a fourteen-year-old, flip-flop wearing, gum-chewing juvenile delinquent. Archie is posing as a female werewolf just for yuks when he meets his 'soul mate' Grimshaw. When Archie's parents kick him out of the house, he finds himself living in a cave on the outskirts of town with his new nemesis Grimshaw. Grudgingly, the two realize that since neither of them have anywhere else to go, they'll have to make the best of it. Over time and through a tragedy that results in near-death of one, the two learn that friendship is the most valuable thing anyone can own.
