Convivial Trio

Chuk Tai-ming elopes to Hong Kong with Shum Tsui-hung in defiance of his father but soon succumbs to harsh conditions and ill health. Shum becomes a courtesan to fulfil Tai-ming's last wish of funding his younger brother Chi-ming's studies in Australia, while creating the false impression that she is a rich widow. Chi-ming returns in summer and a chance encounter in the nightclub evolves into a budding romance. Tormented by a love doomed from the start, Shum pretends to despise the poor suitor. The rejection is taken hard by Chi-ming, who snubs the woman in public. Shum plunges into despair, taking gravely ill. Her lawyer Lee Chung-ling finally breaks the silence, making Chi-ming attuned to the woman's unspoken suffering after she's been laid to rest.

Chan Siu-hung is forced to become a prostitute, with the police following hot on her heels. Ching Chi-ko comes to her defence by claiming to be her husband. Chan is put up at Ching's roof hut named the 'Seventh Heaven' and the two gradually fall in love. Soon the war breaks out. Ching is drafted to do hard labour by the Japanese army. When the war is over, the crippled Ching returns and lies to Chan that he is already a married man, hoping to persvade Chan to marry someone else. Nonetheless, Chan's devotion overwhelms Ching.
