Just before Hein goes on holiday with his father Menno, they receive the message that his grandfather has had an accident and needs care. That's how Hein ends up at the Lommerrust cemetery, where his grandfather is the caretaker. Menno meets his childhood sweetheart Terrence. Hein gets to know her son Jordi, with whom things don't really get along. Then Hein makes a bizarre discovery; he can see ghosts, a gift that he appears to share with his grandfather Johannes. The ghost of Mrs. De Groot asks Hein to free her granddaughter Dewi from the yoke of her strict mother.

In an attempt to get Lommerrust financially healthy, Menno decides to map the dead for whom the burial rights have not been paid. This is not to Johannes' liking, but it also disturbs a ghost from a distant past in his grave. Now that Dewi knows Hein's secret, she is allowed to go on a mission for the first time.
