The Missed Date (1986)

Glamorous Mei builds her entire life around husband Philip, an advertising executive and faithless twerp. She suspects him of fooling around when he pleads working late and having to entertain important clients, and talks this over with Ling, who has a 'modern' relationship with lawyer Ben. Mei is flattered by the attention of Ling's suave cousin Peter, but resists his advances, until confronted by seeing Philip with a lecherous female client. Will Mei retaliate in kind?
