Franklin Stein is a little monster living in the big strange world of the undead. While Frank is always surrounded by his quirky friends, Mumford (a mummy) and Hunter (a werewolf). His sister, on the other hand, Lily, has Ziggy, her giant pet spider, and a zombie genius best friend Abby. Franklin takes on a dare and finds a powerful Dragon's Claw that has the ability to rule the world! Can Voodoo and his slithering side-kick Chopper pass up a chance to rule the world by stealing the Claw, or will Franklin choose family over fortune?
