Meet Mark: an awkward man-child who fibs his way from Indiana to NYC, armed with only a box of childhood memories and a fake forwarding address. His mother, Peggy, believes he's landed a prestigious art gallery job. To afford rent and anxiety medications, Mark becomes a babysitter for an affluent Park Slope family, whose son Milo becomes the only person who accepts this stilted gay man. Well, except for Leather-Man, Mark’s fantasy superhero who materializes thanks to an LSD-laced cupcake. Cubby is a bizarre heart-filled fairy tale for the twenty-something queer kid who comes of age...a little late.
