When middle-schooler Emily Elizabeth (Darby Camp) meets a magical animal rescuer (John Cleese) who gifts her a little, red puppy, she never anticipated waking up to find a giant ten-foot hound in her small New York City apartment. While her single mom (Sienna Guillory) is away for business, Emily and her fun but impulsive uncle Casey (Jack Whitehall) set out on an adventure. Directed by Walt Becker.
