As their empire grows, so do the tensions between the twins, leading to violence and tragedy. Ultimately, their criminal activities catch up to them, and the police, led by detective Nipper Read, work tirelessly to bring them down. The movie ends with Reggie's conviction and eventual release due to cancer, while Ron is declared insane and remains in psychiatric care until his death.
