Old Dag and his two sons Tore and Dag Junior live on Björndal in the Nordic forests. The clan is constantly at odds with the noble landowner Lord von Gall, who lives on his sprawling estate with his daughter Elisabeth. During a dance, Tore snatches the distinguished young lady and sweeps her across the dance floor. Enraged by this audacity, she sets her admirer, Lieutenant Margas, on the temperamental young farmer. Tore loses his life in the fight, and catastrophe ensues.
