Bus Money dons various disguises on public buses to protect the defenceless from the bullies and receives heroic praise. Money meets Tai Ngau, a righteous journalist, when they bear witness to the callous response of Manager Mo to the death of his servant Ah-kwai. Tai writes to redress grievances of the deceased. When visiting the family of orphans, he chances on his kindred spirit giving the eldest daughter Ah-yin a gift of gold. Money exploits the weakness of Mo and her connection with his son Sze-fu to swindle a fortune out of the lewd man for the benefits of the fatherless children. Her rage grows learning that Mo's friend Fong Hak-sang has pulled off a lucrative fraud on returned overseas Chinese and forces Ah-yin to pledge herself in paying off her father's debts. Money, who has all kinds of tricks up her sleeve, teams up with Tai and gives Mo and Fong their comeuppance before setting off on her next mission.
