Driver Ko Wah (Lee Ching) refuses to transport ammunitions for the enemy, and is sent to jail after a scuffle with his traitorous boss. Although down and out, Ko takes in Siu-fung (Yung Siu-yi), an unwilling erotic dancer who has fled the war to Hong Kong. They may lead destitute lives, but their conscience remains intact. Director Cai Chusheng co-founded the National Salvation Association of Cinema. When Ko makes a uproar at the dance parlour and rips apart his friend's zombie costume, it represents Cai's criticism on the muddling-along attitude of Hong Kong society at the time. The characters' decision to return to the mainland to join the resistance effort also foretells Cai's decision to do the same in real-life.

Law Hing is forced by her stepmother to marry the dumb son of the Tang family. Another girl Au To is forced to marry Ma Siu-fuk, son of the rich Ma family, to pay off her father's debts. On the wedding day, To's lover See Fuk-chau returns from Vietnam. Deeply in love with Fuk-chau, To decides to go to the Ma family to decline the arranged marriage. To avoid the Ma elders and her father from losing face, she begs Siu-fuk to stage a pretended marriage. As the wedding ceremonies proceed, To's bridal sedan collides with Hing's in the street. The carriers lock in a row and a confusion reigns in which the brides take the wrong sedans. To is mistakenly taken to the Tang family, while Hing is sent to the Ma family. Although Siu-fuk is attracted to Hing, he agrees to send her home. The four families attempt to settle the case in court. The judge rules that the previous arrangements are but trades and declares them null and void. Fuk-chau and To can now fulfill their wish.
