Shadow(1982)

Shadow is a Thai supernatural drama following Wasawat, a devil tasked with punishing sinners after living a life of equal good and evil. Trapped in his role, Wasawat seeks someone morally balanced to replace him—someone neither wholly good nor bad. He targets Isara, a man whose moral ambiguity mirrors his own, believing him the perfect successor. But Wasawat's plans unravel when he confronts Isara's love for Charoenkwan, forcing him to abandon his scheme. Complications deepen as Wasawat's shadowy past entangles him with Chalinee, Isara's half-sister, and the web of secrets threatens to consume them all. The series explores redemption, moral compromise, and the cost of second chances in a world where no one escapes their past.
