Whenever danger strikes, it frantically rewinds time. The tyrant Xiao Xi is driven to distraction by this "sorcery," trapped in a loop of his own making. In desperation, he summons the Imperial Preceptor to perform an exorcism, only to get sprayed in the face with ink again and again. His sanity finally snaps.
Convinced this bewitching consort has profound powers, he can only give in to her demands one step at a time. But as they spar, he gradually falls for her. In the end, the mighty tyrant falls into the hands of this "demon."
