Heddi is a self-confident and battle-hardened coastal fisherwoman. She only has one weak point: her daughter Eva. Eva is an environmental activist and just as militant as her mother. But despite their resemblance, Eva doesn't want to know anything more about Heddi; there has been radio silence between the two for years. But now Eva and her ten-year-old son Jannis turn up unexpectedly in the small Baltic Sea village, ostensibly for a birthday visit to Grandma Lore, where Eva spent most of her childhood. In reality, however, Eva is in big trouble: She has to serve a prison sentence for resisting law enforcement - and a repeat offender at that! - she has to serve a prison sentence. But who will look after her little Jannis while she is away?
