A young boy in the 1950's sees a car for the first time. This brief moment turns out to be something not so easy to forget.

Bachelors Pekka Puupää and Pätkä are going to a dance. There they meet Justiina Pönttö. Pekka and Justiina hit it off and get married as soon as possible.

The police need temporary help due to illness, so Pekka Puupää and his neighbor Pukkila sign up as temporary police officers. Soon, the bumbling duo finds themselves in the middle of a kidnapping case.
