In accidentally stumbling upon a time tunnel while studying art, the great Kung Fu master Huo Yuan Jia crosses through, from the Qing Dynasty to modern day. Dazed and befuddled by the difference of visible stars above, Huo Yuan Jia comes across Ah Kuo, Hsiao Yu and Fatty, who not only help him escape pursuing secret agents,, but also find the time tunnel so he can return to his own time- not before the boys thwart the conceited enemy though.
