At the end of WWII the Dutch resistance kills a German officer in front of the house of a Dutch family. Years after the war the young boy who witnessed the killing runs into the members of the resistance who committed the killing.

Tim, now a respectable family man, runs into his old buddy Bodde. Bodde convinces Tim to go out with him under the motto: "Laugh, laugh, laugh!" Tim calls his wife to tell her "he'll be a little late," while Bodde keeps persuading him to stay with him for a new deal or a wonderful plan, and so they roam the country. Along the way, they swindle money from everyone and meet the young, beautiful Aafke. Isn't Tim too old for all this?
