Van Der Valk is contacted following the death of a young woman in the vicinity of a library and museum, owned by a wealthy philanthropist, that specializes in the promotion of global mysticism. The investigation will bring him and his team into contact with a nun interested in erotica, the followers of an obscure Christian sect that worship the wounds of Christ and a drug facility with a controversial approach to addiction as well as going to the heart of a longstanding family feud.
