37-year-old female teacher Viona (Marika Lagercrantz) is beautiful and charming. Her husband, a stockings salesman, is on business trips all day. Even when he comes home, he just listens to music and drinks, which makes her feel very lonely. 15-year-old teenager Steve (Johan Widerberg) in the class is ignorant and has the unique impulse of adolescence. The moment the teacher and the student look into each other's eyes, a mutually dependent abnormal love naturally arises. When they are completely immersed in the pleasure of carnal desire, Steve has no interest in girls of the same age and refuses the secret love of his classmates. Viona's husband actually knew his wife's secret a long time ago, but he did not reveal his wife's secret, but continued to drink and listen to music. This situation made Steve begin to reflect on his own carnal desires and this abnormal love.
