Rouge

Chan Chen Pang, better known as the "12th Young Master", was a fashionable playboy who frequented the opium dens prevalent in Hong Kong in 1934, where he met the high-class and much sought-after courtesan Fleur. They began a passionate love affair, something frowned upon by the family of 12th Master, who held sway over the business of the area. Clearly, their love was doomed when it was found out. Seeing no way to pursue their love in life, on March 8 at 11 pm, the couple resolved to commit suicide together by swallowing opium and promise to meet again in the afterlife. After waiting for Chan in hell for 50 years, Fleur returns to the world of the living to look for him, wondering why he has not emerged. A spirit now, she searches for her lover in a Hong Kong she no longer recognizes...
