Brief Encounter in Shinjuku

Leung Foon (Lawrence Cheng), Q Tai-long (Manfred Wong) and Pierre (Peter Lai) bring their wives/female companions to a trip sailing in the sea. Halfway during their trip, Ann (Carol Cheng) encounters her ex-boyfriend, Alan (Allan Fung). Alan is a Médecins Sans Frontières who has been stationed in Africa. Alan intended to invite Ann to Africa but was rejected. Ann also rejects her superior, KK Yeung's (Eric Yeung) offer to immigrate and work in Australia and decides to reconcile with Foon.

Foon and Q Tai-long transfers to a new company where they meet new secretary Wendy Wan (Rosamund Kwan). Leung's boss, Mr. Tsang (Kenneth Tsang), assigns Foon and Wendy to a business trip in Shinjuku, Japan. After the two arrive in Shinjuku, they realized they have forgotten to bring their proposal and had to work all night in the hotel where Wendy eventually becomes exhausted and falls asleep. The next day while meeting their client, Foon presents an outstanding performances which attracts Wendy. The two go out for shopping afterwards where Wendy gets on the wrong tram ride and Foon rushes to rescue her. Foon nearly spent all his cash on taxi rides to find Wendy and they eventually use a credit card for a final ride back to their hotel. Back at the hotel, they get intimate with one another and make love. The next day, the two make a call back to Hong Kong informing their boss that they have not yet completed their assignment and must stay for one more day as an excuse for them to spend a sweet day in Tokyo.

After the two return to Hong Kong, their intimate relationship becomes gradually exposed. Finally, at the wedding of Wendy and her boyfriend, John Li (Lee Chung-ling), Foon arrives late and trips at the door which causes his fingerprints to be printed on Wendy and John's marriage certificate. Foon also admits to Ann about what happened to Ann and was kicked out by Ann as a result. Foon later receives a call from Wendy to meet at the outside of the Legislative Council building. There, Wendy tells Foon that she told John about their intimate relationship which John is unable to accept and helplessly left him. She also tells Foon that she will keep the marriage certificate since it has Foon's fingerprints on it.

On the other, because Q Tai-long became involved with Pierre's girlfriend, Fanny (Vindy Chan), his wife, Fung (Leila Chow), leaves him and their son. During one occasion when Foon, Pierre and Q Ta-long were eating instant noodles at the latter's home, Fung returns to cook dinner for them and stating that she is doing it for her son and Q Tai-long is overjoyed. At this time, Foon is also determined to reconcile and repair his relationship with Ann.
