A group of students investigates a series of mysterious bear killings, but learns that there are much more dangerous things going on. They start to follow a mysterious hunter, learning that he is actually a troll hunter.

When bears are found dead in Norway, students from Volda University (Thomas, Johanna and cameraman Kalle) decide to investigate. They stalk the trail of the mysterious hunter Hans, expecting to find an explanation for the killings. The reluctant Hans tries to flee from the youngsters but then agrees to let them film him in action, provided they follow his orders. Soon the trio of students learns that Hans is actually a troll hunter working for a secret government agency. Further, several dangerous trolls have escaped from their territory and Hans is assigned to eliminate them.—Claudio Carvalho, Rio de Janeiro, Brazil
