Sensible Bavarian veterinarian Nina Sander fits dresses for her registrar's wedding with even more pragmatic Munich businessman Paul. Suddenly she's called away: aunt Charlotte Berger, who raised her when orphaned, has a mild heart attack. Charlotte implores her to reconsider the marriage and moves back home dangerously soon so Nina stays to mind her. Charlotte keeps pushing her to her summer lodger, widower painter-sculptor Daniel Roth, who has trouble keeping his and angelic son Miki's home on Fraueninsel in lake Chiemsee. Charlotte also hides a secret for both of them.
