Half-senile Ossi and his wife travel to celebrate Ossi's 75th birthday at an old people's home where most of their friends are already staying. Just before the festivities Ossi suddenly disappears and goes on tour to 'make an inventory of his life'. He checks into a hotel, poses as a publishing director to lure an aspiring female novelist, next travels to bother his old mistress and her new husband with his surprise visit and obnoxious comments, then goes to see his son for the first time in 34 years just to receive an even colder treatment. Meanwhile, his equally demented wife goes looking for him with a local policeman.
