Uuno Turhapuro armeijan leivissa

Uuno is called to serve the rest of his military service. His father-in-law, Director Tuura has been appointed as a defence minister but he hasn't got any interest to free Uuno from his service. Tuura orders Uuno to army immediately to get a rest from him for a while. In the army Uuno makes the officers go mad and soon he is been transferred as a horseman.
