At this moment, Charlotte (Christa B. Allen) was taken away for questioning on suspicion of drug use. The returning Victoria (Madeleine Stowe) and the white-headed man seemed to be planning a new conspiracy, and the undetermined baby in Amanda's (Margarita Levieva) belly. Under the turbulent clouds and angry seas, it is Emily's determination to pursue the truth that never stops, and the fangs that are ready to launch ruthless revenge at any time and anywhere. Deep hatred and greed and selfishness have dragged all the people involved into a whirlpool that cannot be extricated... This film is adapted from Dumas' classic masterpiece "The Count of Monte Cristo".
