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.
