Tsao, the emperor's first eunuch, has successfully bested General Yu, his political opponent. The general was beheaded but his remaining children have been exiled out of China. As the children are being escorted to the western border of the Chinese empire, Tsao plots to have the children killed. Tsao's secret police lie in ambush at the desolate Dragon Gate Inn. Martial arts expert Hsiao shows up at the inn, wanting to meet the innkeeper. Unknown to the secret police is that the innkeeper, Wu Ning, was one of the general's lieutenants and has summoned Hsiao to help the children. A brother-sister martial-artist team (children of another Yu lieutenant) also show up to help. These four race to find Yu's children and lead them to safety. (Source: Wikipedia)
