Henk van der Pol is a 30 year term policeman, a few months off retirement. When he finds a woman's body in Amsterdam Harbour, his detective instincts take over, even though it's not his jurisdiction. Warned off investigating the case, Henk soon realizes he can trust nobody, as his search for the killer leads to the involvement of senior police officers, government corruption in the highest places, Hungarian people traffickers, and a deadly threat to his own family.
