The dynamic duo of Chon Wang and Roy O'Bannon go back for yet another experience. This time around, they're in London to avenge Chon's father's murder, but end upon an instance. Chon's sister would be there to perform the same, however as an alternative unearths a plot to kill the imperial family. Nobody thinks her, however, and it is upto Chon and Roy (who's love in his mind) to establish her right.
