It's Christmas Eve at the Harper house, and young Ryan and Casey are excited that their scientist father (Mackenzie Astin of ''The Facts Of Life'') has finally perfected his new invention! But when dad is kidnapped by a bumbling gang of thieves (led by Jeffrey Combs of Re-Animator), Casey's wish on a magic doll causes Santa to leave behind a mischievous elf ('Wee Man') to save the day. Will Santa's little helper lose all faith in his elf self, or can he discover his true powers to become a real superhero? Mirelly Taylor (''Lost'') co-stars in this big-hearted family comedy about holiday wishes, scary fruitcakes and Christmas miracles that come in every size!
