In a small mine town north of the circle, Torsten lives, working with his sister Eva and comrade Lars, who is engaged to Eva. The town's bat-owner has a daughter, Märta, who, after trying out the big city life, has returned to the village for a while, and begins to flirt openly with Torsten, but also with Lars. Märta hears of an old gold treasure that will be hidden somewhere in the mountains, trying to seduce both of them and seek both friends to find out the treasure. Neither Lars nor Torsten knows the plans or swarms of others, but Eva notices how Märta attracts Lars away from her.
