Orphaned on the streets of Manhattan, a cat named Chester begins a life-changing journey to a dark wetland forest on the coast of Maine. There he befriends an abandoned cat named Patches whose father had disappeared in the forest. An ancient neglected graveyard, sketches by a young artist revealing the secret of a lost father, a life-threatening blizzard, the arduous search for a missing friend, the struggles of a feral mother cat with her four kittens, and terrifying encounters under the halo of a moonlit night are all manifestations that forever change Chester's outlook on life.
