Full of envy for the highly regarded Luk-wan, eunuch Bat Lap leads him into the forbidden Bak-fa Pavilion, where trespassers are punished and beheaded. Prince On-sai’s daughter practises fencing at the pavilion, which is off-limit to all males.

When the prince finally revolts, Fa-lung has Luk-wan unwittingly pass misinformation to the princess, lowering her guard. The surprise attack by Fa-lung that night wipes out the army of Prince On-sai. Although the wounded princess breaks through the siege, the prince and Bat Lap are captured.
