Lady Pearl, granddaughter of the gang's founder Iron Bodyguard, objects to Roast Pork's nomination as the next Don because the position was promised to her son Swallow by Uncle Tsa in return for Swallow serving a 20-year sentence for a gang killing he performed.

Uncle Tsa suggests that the person who retrieves the gang's symbol, the Dragon Tail Baton, from the police should be made the next Don.

Swallow is uninterested in the position and wants to go to college instead, but his interview with Hong Kong University is sabotaged by his faithful underlings and his mother, who needs him to remain in the gang so that she has a source for her various drug habits.

Roast Pork pays to have fake Dragon Tail Batons made out of the wood from an antique chair.

Uncle Tsa can't remember which one is real, so the two contenders battle for the position of don, shooting and killing each other.
