To escape his responsibilities, Alby (Matt McGrath) embarks on a life-changing trek through Central Florida with his childhood friend, Elias (Judah Friedlander), to Diggityland, the theme park they loved as kids. On the way, ragtag characters show them the importance of moving on. Their journey takes an unexpected turn thanks to a whacky mermaid (Deborah Harry), a bitter ex-theme-park worker (Alan Cumming) and a clown bartender (Amy Sedaris).
