Sinopsis

Cheng, a beautiful martial arts ace, battles to keep her inheritance from the ruthless Yun Wei, but her efforts are sabotaged by Yu Tao, her wayward and irrepressible great-nephew. Following a frenzy of spectacular comic mishaps, the hapless duo are setup and imprisoned and the deeds to Cheng's estate are stolen. She is held hostage after a doomed attempt to reclaim the papers back from Yu Wei's place, and the stage is set for a savage fight to the death.
