Feng Kuang De Shi Tou plot
A very precious jade is found in a (almost bankrupt) factory. The director decides to put the stone on display to raise money and save the factory. He appoints one of his employees, ex-detective Bao, to manage the security. The poor man, who is struggling with prostate problems, soon has his hands full with an incompetent trio of thieves, a professional burglar and the director's son, who all want to get their hands on the stone.
