Live action kiddie entertainment about two tribes of trolls fighting for control of a Magic Ring. The good witch Tikla meanwhile holds on to the Ring. Viktoria, an underground Troll child, is forbidden to visit the above-ground Trolls, but does so anyway. She meets Viktor and together they go through an array of dangers before they chance into Tikla's den. She gives them the Magic Ring so that they can mediate a truce between the tribes.

At age 12, Lasse is a tough guy and a bright one. His life is changed when his mother, pregnant at the time, abandons his beloved father. She takes Lasse with her to live with her new paramour, a dentist as authoritarian as Lasse's Elvis Presley-fan butcher dad was easy-going. The dentist has a daughter, too, and she is a jealous schemer. Lasse tries hard to conform, but can a tiger change its stripes?
