tl;dr: Lesson in Murder is a psychological thriller that culminates in a shocking twist where the protagonist, a brilliant but troubled detective, discovers that the serial killer he's been hunting is actually his own repressed alternate personality. The film ends with the detective confronting his dark side in a climactic mental battle, ultimately choosing self-sacrifice to prevent further killings. The ambiguous final scene leaves viewers questioning whether the cycle of violence will truly end or if the killer's influence lingers.
The Ending Explained
The finale of Lesson in Murder is a masterclass in psychological tension, revealing that the detective, David Mercer, has been unknowingly committing the murders he's been investigating. Throughout the film, subtle clues-such as blackouts, misplaced evidence, and eerie familiarity with crime scenes-hint at this revelation. The turning point comes when David finds a hidden journal in his apartment, filled with meticulous details of the killings in his own handwriting. The film's climax occurs in an abandoned school (a recurring symbolic location), where David confronts his alter ego, "The Teacher," a manifestation of his childhood trauma and suppressed rage.
The confrontation is both physical and metaphysical, blurring the lines between reality and hallucination.

As he bleeds out, the camera lingers on his face, showing a mix of relief and sorrow. The final shot cuts to an empty classroom, where a faint whisper echoes, suggesting that "The Teacher" may not be entirely gone. This ambiguity fuels debates about whether David's sacrifice was enough or if the cycle will continue through another vessel.
