A prehistoric bog body dug up by archaeologists turns out to not only still be alive, but is actually a hairy humanoid from another dimension named Iau (Kevin Nash).

Sequel to "King of the Trees". Iau returns still trying to find his way back to his native dimension, with Merkel (Antoni Corone) in pursuit. It only gets worse when the SPLAT squad accidentally injures a dying boy who has befriended the hairy giant.
