According to an old Scandinavian folklore legend, a Berserker (Viking) was a bloodthirsty warrior who ate human flesh, forbidden a restful death and fated to be reincarnated in their blood kin. A summer camp accidentally stumbles across the Berserker legend when it arises in Rainbow Valley, an area settled by Norwegian immigrants. The camp is abuzz with rumours of a wild bear killing people in the area, including speculation about an old couple who get lost. But is it really a bear?
