KONG KWAN CHING and CHAN TAT CHOI are working for Tin Lung Advertising Company. Since the business is declining, KONG and CHAN go for account-pitching by all means, yet their effort is futile. KONG's wife WAI KWAN leads an extravagant life and she squeezes her husband like lemon, thus KONG is under unbearable mental and economical pressure. In order to fight for accounts, KONG and CHAN are tired out by keeping constantly on the run to win over a big Japanese account. At the same time, CHAN becomes familiar with KONG and he takes this opportunity to start his courtship for WAI KWAN's sister WAI MAN.
