The burglar Karl Kilian Ledig tries to get his somewhat reluctant son Carl Gustaf interested in his "profession". He bring him along one evening to the sculpture Ulla-Carin von Knaake's house to break in and steal from her safe. Complications arise when Ulla-Carin and some of her friends unexpectedly come home and she imagines that Carl Gustaf is a model she has hired from a model agency.
Bosse enjoys life and summer in a small cabin, he longs for Lajla who promised to come. The calm does not last for a long time, but soon one personality comes after another.
