Half a body is not half a mystery. Sam Jeffery's friend has been killed and someone made off with half the body. Or did they? Sam Jeffrey knows the Minnesota woods. He's spent his entire life in them. There should have been sign of a struggle or get away, but there's nothing. When the police discover the severed head of a giant reptile, Myra Tolie, an archeologist specializing in dinosaurs from the Science Museum of Minnesota, is brought in to help identify it. Excited by the discovery, she heads to the Paradise Palms trailer park to see if there could be a hidden nest of dinosaurs living there. Strange occurrences draw together several members of the trailer park to find out what is going on and how to stop the trailer pack from teleporting back in time.
