Two sister acrobats, Meng Yu Yieh (Ivy Ling Po) and Meng Yu Ying (Wang Ping), arrive in a town known to be rich in silver and gold. They do street performances and dangerous sword stunts until Yieh is apparently injured. In the emergency they are taken into the nearby treasury house. Chief treasury guard Wen (Richard Chan Chun) determines her injuries are fake and a fight ensues.
The film's original Mandarin title was Huo bing, its Hong Kong Cantonese title was Fo ping and the working English language title Thieves Fall Out. After release the film's worldwide English subtitled version was titled Duel for Gold.
