The murder of a debt collector working for a housing association turns out to have far-reaching consequences. The man, a refugee from Bosnia, is not as innocent as he appears to be. While clearing cannabis plantations, Marion and Romeo are approached by a man who claims that his disabled parking space has been stolen by loitering teenagers.

Wolfs and Eva are added to an Amsterdam team that is eager to make a big drug bust in Maastricht. Wolfs doesn't trust Eva around heroin and assigns her to work on something else. He shouldn't have done that, because the arrest turns into a shootout in which one of the Amsterdam detectives is killed by a bullet from Wolfs' gun. Romeo has completed the leadership course and has developed a good relationship with the course leader.
