Uuno Turhapuro is searching for a job and takes a correspondence course in tour guiding. Eventually he gets a job in a small travel agency and takes a group of Finnish tourists to Marbella, Spain. Unfortunately Uuno's father-in-law Tuura is in the group, too, with his wife and daughter, Uuno's wife Elisabet. Tuura tries to get a signature to an important paper from a minister who's having a holiday in the area. Meanwhile, Uuno just relaxes and enjoys the sun.
Uuno is unemployed and his friends try to arrange a job for him. With his imagination, though, and the help of Härski Hartikainen (Spede Pasanen), he somehow manages to avoid all work, until he becomes what he has always dreamt of being - a film star. Uuno's father-in-law has other plans for his occupation, though: since Uuno knows the Dandelion, he has potential for a professor of botany.
Uuno is forced to complete his mandatory military service when it is revealed that he only spent one day in the army in his youth. As is typical of the Turhapuro series his family and friends become closely tied in with these events. His friends Härski Hartikainen and Sörsselssön return to the army for a refresher course and by chance Uuno's father-in-law, Councillor Tuura is made the Finnish Defence Minister. In one of the most memorable scenes, Uuno's wife, Elisabeth, dresses as Uuno and substitutes him for a day as Uuno has an apparently urgent meeting (at a restaurant) and while becoming lost in the woods with a malfunctioning radio, Tuura accidentally declares war on Sweden.
