Sebastian Ko's Der Amsterdam-Krimi: Die letzte Zeugin brings special investigator Alex Pollack and inspector Bram de Groot into a network of human trafficking and illegal organ trading. Hannes Jaenicke and Fedja van Huêt return in a case whose central witness is also its most vulnerable target.
Safiya and her younger sister have been brought illegally into the Netherlands. The supposed price of a new life is a kidney. Safiya escapes, but her sister remains trapped. Meanwhile, Pollack and de Groot investigate gangster Irfan Dewi, who is on trial and appears determined to silence witnesses. Safiya could become crucial to the case, which makes her safety urgent.
The film works less as a conventional whodunit than as a thriller. The perpetrators become visible early; suspense comes from whether the investigators can break the network in time. Ko uses dark images and an abrasive Amsterdam far removed from postcard romance.
Shanaya Dap is especially strong as Safiya. She plays a determined young woman with a perspective of her own, rather than only a witness needing protection. Jaenicke benefits from Pollack's emotional involvement, while van Huêt provides a calmer counterweight. The familiarity of their friendship sustains the series even when the case becomes expansive.
The difficult subject works best when its moral horrors emerge through individual figures rather than a checklist of issues. Some situations are nevertheless heavily constructed, some characters serve mainly a dramatic function, and the action does not always have the impact the material suggests.
Die letzte Zeugin is a dark, socially charged thriller with pace, atmosphere and a strong central figure. Not every turn convinces, but it is considerably more ambitious than routine television crime drama. I give it 7 out of 10.
