Eliot Shag falls asleep at his animation table after a long, hard day drawing a new Ace Hart Adventure. Pretty soon a cartoon Eliot joins Ace in his animated world, out of Eliot's dreams. Ace and Eliot reluctantly team up and end up in a wacky, surreal parallel dimension that's a creation of Eliot's subconscious. As Eliot follows Ace through Dog City, Eliot gets to know all of his characters up close and personal. The adventure takes a turn for the worse when Eliot disappears and Ace Hart is charged with dognapping him.
