The decades spanning story of two very different policemen who rise to power in Hong Kong during British rule, and end up at odds with both organised crime groups and the anti-corruption unit vowing to bring them down.
Adapted from a sensational real-life case in 2013, the intricate story begins when a young man partners with his friend to murder and dismember his parents. Pleading not guilty, the defense attorneys soon turn on each other, as the defendants play the devil and idiot game. Meanwhile, heated debates emerge inside the jury room, where nine jurors grapple with the truth.
