On a quest with buddy Rizzo to find his real family, Gonzo discovers that his long-lost relatives are actually aliens from a distant planet. After announcing to the world on Miss Piggy's talk show, "UFOMania," that he is living proof that "we are not alone in the universe," Gonzo becomes the target of paranoid government operative K. Edgar Singer (Jeffrey Tambor). In the end, Gonzo must not only escape the Singer compound, but decide to either board the mother ship and join the family that he has always wanted, or stay on Earth with the friends that he has always known and loved.
