Celebrity Sadora is seriously wounded in an air crash. Police commissioner Suen and subordinate Ko Cheung find out Sadora was under duress from the Black Dragon Gang to collude with the criminals who had held his daughter hostage. When Ko, assuming Sadora's identity to safeguard his life, is abducted by the gang, Suen turns to 'Black Musketeer' Muk Lan-fa. By blatantly refusing to cooperate with the authorities, Muk escapes the surveillance of both the police and the gang. Acting alone, she scouts the location of the lair but ends up being imprisoned in the same cell with Ko. The captives use every trick in the book to escape. An undaunted Muk returns to infiltrate the den, while her sister Sau-chen, Suen and Ko are lying in wait. The hostages are released and the gang wiped out in a battle fiercely fought.
