In the waning years of the Ming Dynasty, the Bruneian Empire offers a rare creature to the nation as a gift. Ocean, a member of the Imperial Secret Police, has been tasked to tame the beast. Though the furry beast appears ferocious on the outside, Ocean discovers that it is kind by nature. Not wanting to turn the beast into a killing machine on the battlefield, Ocean secretly releases the beast into the wild and elopes with Frigid, the daughter of a man executed on false charges.
