Hong Kong sci-fi martial arts action. It's Armageddon on Earth as the four Gates of Hell begin to open up in the unlikeliest of places. The first gate unleashes the combined demonic forces of the dangerously sensuous Hell's Witch, Raga (Pauline Wong), and the sexy but deceptively coy Hell's Virgin, Ashura (Gloria Yip), whose mission is to ensure the subsequent gates are allowed to open without resistance. According to legend, the opening of the fourth gate will set loose the King of Hell himself upon the earth and cast the world into infinite darkness. Mankind's only chance of survival lies in the hands of two amiable monks, the Chinese Peacock (Yuen Biao) and his Japanese counterpart Lucky Fruit (Hiroshi Mikami), each endowed with magical skills and a dazzling array of martial arts skills.
