Olavi, a farmer's son, leaves his home after a dispute with his father and leads a life of a womanizing logger.
Sylvi's child is run over by a bus, prompting her to drink poison. She goes blind in the process, causing her husband to lust after her much younger sister. After undergoing a dangerous operation to regain her sight, she hides her repaired vision behind dark eyeglasses, so she can spy on her sister and husband as they carry on their affair.
The film revolves around Vihtori's clandestine involvement with an attractive and rather worldly young woman named Ritva, who is planning to marry boxing champion and garage owner Klasu Tullari, son of Vihtori's friend Tomi, and their interactions with daughter Vappu and her fiancé, Peter von Schaslick, a mechanic in Klasu's garage, under the nose of the threatening and suspicious Klaara, with lazy son Nisse acting as a rather sardonic Greek chorus. Teuvo Tulio's only comedy.
