Wolfs en Eva investigate the murder of a Turkish drug cartel member. His gang seems to have become victim of a rip deal. Meanwhile, a worried father asks Marion and Romeo to track down his daughter's cyber bully.
A rock band member dies from what appears to be a drug overdose. The medical examiner however believes he was murdered. Wolfs and Eva try to find out who had a motive. Marion and Romeo are meanwhile taking care of an autistic man.
A man has been murdered in caves, formerly used as NATO air space surveillance bunker. The only traces are to a gang which committed a diamond robbery years ago, loot still missing, and Jimmy Waters, from Ohio, whose father once worked in the cave facility. Floris is rather distracted as his daughter Fleur is tried and convicted gravely for violence on an erroneous victim.
Duorng an investigation, not even confided in Eva or prosecutor Jens Bols, linking 'closed' crimes trough Mered Aysin's Turkish mob, Floris makes a bad fall chasing a Dutch deputy, who captures him to be tortured. Romeo must deal with the case of an adolescent father's complaint to be beaten by his father, which soon proves improbable, rather inspired by his parents's bitter separation.
After the Turkish mob boss's deputy's suicide killed that case, Floris confides in his colleagues that he suspects several seemingly closed cases to tie together in the person of prosecutor Jens Bols. Flirting with illegality and grave procedural error, he sets a trap. It proves that the drug gang, which steals its truckload of weed back, is linked with Italian mob arms traders, but those come heavily armed too eliminate all witnesses.
