Niklas Siebert is finally finding peace of mind. After the death of his father and period of conflict with his sister Freya, peace has only recently returned to the family. As has the routine they had long desired. And as far as the Fischerfleck is concerned, it is now so much more than just an inn by the lake. It’s become a hotspot where not only the beautiful and rich of Munich go on vacation, but also the locals – something that Niklas and Freya worked hard to achieve. They still dearly need their energy for the inn – and Niklas also needs it for commercial fishing on Lake Walchen, which he wants to scale up while ensuring that it's also environmentally friendly. He doesn't want any more excitement. But just after celebrating Freya's 30th birthday, Pia Kaufmann is suddenly at the door announcing that she is moving back to Lake Walchen for business reasons and bringing her fiancé with her. The woman who broke Niklas' heart many years ago is back. Will his new relationship with veterinarian Jessica be able to survive? And what exactly is Pia's fiancé planning?
