I Hate Kids follows Nick Pearson, a former lothario and author of the title best-selling memoir, who has everything he wants. He’s about to marry the woman of his dreams, Sydney Bartlett, who shares his disinterest in becoming a parent. But just days before their wedding, he’s shocked to find out that he has the one thing he never wanted: a child.
Nick’s happy, child-free existence is put in jeopardy when awkward 13-year-old Mason interrupts the engaged couple’s rehearsal dinner and claims to be the groom-to-be’s son. With the aid of flamboyant radio show psychic The Amazing Fabular, who claims he helped Mason find his father after having a vision about them, the three strangers embark on a wild road trip to find out which of a dozen eccentric women from Nick’s past could possibly be Mason’s mother.
