Sweethearts (1970)

Suse and Ulla are happy together. They live in the country with Ulla's son Karl and enjoy the summer. One day Tom comes by. Tom is Suse's ex - and he is on his way to a rehab clinic. But over the course of the morning it becomes clear: Tom is not yet really comfortable with the fact that Suse has split up with him. And Suse's hope that Tom has grown up a little bit through the planned rehab is soon dashed.
