Move over, Harvey, you've got competition! Eight-year-old Toby (Leo Millbrook) has a problem: His creepy Aunt Violet keeps trying to snooker him out of his inheritance, and she'll stop at nothing. Fortunately, Toby also has an ace in the hole -- Lucky, his invisible magic dog, a mutt no one else but Toby can see. Doggone! Also stars Russ Tamblyn.
