Päiviö Pyysalo

Uuno Turhapuro's younger brother Peni arrives in Helsinki. Uuno helps his brother in management duties.

Uuno is working as campaign manager of a president candidate but accidentally Uuno himself becomes the president of Finland.

The film is based on characters from the Mänttien TV-asema sketches featured on the Spede Show.

'Tup-Akka-Lakko' is a sequel to 'Koeputkiaikuinen ja Simon enkelit' in which doctor Jyrä invented a test-tube-adult who looked exactly like Mutikainen, a mathematician. When the test-tube-adult's body emerged, his voice moved into Mutikainen's body because of the doctor's error. Problems ensue.
