Patrick Alexander thinks he's going crazy. At age 30, he's frustrated with his life in the small Mississippi town where he grew up, stifled by his unhappy marriage and his soul-crushing pizza-delivery job. But when he drinks, his world becomes populated with the hallucinatory characters he invented as a child, including a Martian and a talking monkey. In the midst of an existential crisis, Patrick leaves his wife and the only home he's ever known to embark on a spiritual quest where he will find new loves, face his long-missing father, and confront the demigods of his personal mythology.
