During a rehearsal of Maastreechter Staar, a choir member is poisoned. When it turns out that the poison was in a chocolate egg that was served during the coffee break, it is up to Eva and Wolfs to find out what is going on. It soon becomes clear that the entire choir is being threatened on their social media. Romeo and Marion investigate a number of burglaries in an expensive neighborhood. Remarkably, none of these burglaries set off an alarm. And things are not going well for Nico.

A walker catches a man burying a dead woman. The man runs away. The woman's body has been thoroughly cleaned and cannot be identified. Marion and Romeo have to update their administration, according to the pressured Zitman. Fortunately, they are asked to help Wolfs and Eva search for a girl who may have seen the perpetrator. That puts them on the trail of a loverboy. Nico has made a weighty decision.
