tl;dr
The ending of The Treatment (2014) is a psychological thriller that concludes with Detective Nick Cafmeyer confronting the pedophile serial killer Ivan Plettinck, who had tormented him since childhood. After discovering Plettinck's latest victim alive but traumatized, Cafmeyer executes him in a moment of rage, breaking the cycle of abuse but also crossing a moral line. The film leaves audiences questioning justice, vengeance, and the lingering scars of trauma, with Cafmeyer's fate left ambiguous as he drives away, haunted by his actions.


Detailed Ending Explanation
The Treatment builds toward a harrowing climax where Detective Nick Cafmeyer finally uncovers the truth about Ivan Plettinck, the man who abused him as a child and is now implicated in a series of horrific crimes against children. The film's ending is a visceral culmination of Cafmeyer's lifelong trauma and obsession with Plettinck. After a tense investigation, Cafmeyer locates Plettinck's hidden dungeon, where he finds a young boy, Ben, alive but severely traumatized. This discovery confirms Plettinck's guilt and reignites Cafmeyer's unresolved rage. In a moment of cathartic violence, Cafmeyer shoots Plettinck, ending his reign of terror but also committing murder. The film's power lies in its moral ambiguity: Cafmeyer achieves justice but at the cost of his own humanity.

Themes of Justice and Vengeance
The ending starkly contrasts legal justice with personal vengeance. Throughout the film, Cafmeyer is frustrated by the legal system's inability to punish Plettinck adequately, mirroring his childhood powerlessness. By killing Plettinck, Cafmeyer takes justice into his own hands, but the act is framed as both triumphant and tragic. The film suggests that while Plettinck's death is deserved, Cafmeyer's actions leave him morally compromised. The final shot of Cafmeyer driving away, his face a mask of exhaustion and guilt, implies that his trauma will persist despite his revenge. This ending challenges viewers to consider whether true closure is possible for victims of abuse or if the cycle of violence is inescapable.

Psychological Impact on Cafmeyer
Cafmeyer's character arc is defined by his obsession with Plettinck, and the ending forces him to confront the futility of his quest. Killing Plettinck doesn't erase his childhood trauma; instead, it adds the weight of murder to his conscience. The film's bleak tone underscores that revenge is a hollow victory. Cafmeyer's final moments are devoid of relief, suggesting that his actions have only deepened his psychological wounds. The absence of a clear resolution-whether Cafmeyer will face legal consequences or continue to spiral-adds to the film's unsettling realism. It's a poignant commentary on how trauma reshapes identity and the limits of catharsis.

1. What happens to Cafmeyer after the murder?
- He may turn himself in, grappling with his guilt.

Personal Opinion
The Treatment is a brutal but compelling exploration of trauma and justice. The ending is fittingly grim, refusing to offer easy answers. Cafmeyer's moral descent is heartbreaking yet inevitable, reflecting the film's bleak worldview. While some may find the resolution unsatisfying, its rawness is what makes it memorable. The film's unflinching portrayal of abuse and its consequences lingers long after the credits roll, cementing it as a powerful, if disturbing, psychological thriller.
