Paralyzed after a car crash that killed his wife, billionaire Xavier can't prove the man playing his “devoted son” Leo is actually the killer. So he plays the confused old fool—drugged by beauty, losing his mind. Secretly, he teams up with Myra, a young woman he once saved, and his asset manager to set a trap on live stream. At the inheritance meeting, he leaves everything to Myra. The internet explodes: “Disgusting old man!” Meanwhile, Leo plays the perfect son—urine bags, feeding, rehab, even a kidney—winning hearts. But Myra? She's a lawyer collecting evidence. Piece by piece, the truth drops: DNA, hallucinogens, crash evidence. Leo isn't just a fake son—he murdered Xavier's wife, Amber. Cops take him down. At Amber’s grave, Xavier finally clears his name. Ten years of shame, one perfect revenge.
