JON is an executive who works in a PR firm. He has been happily married for two years but has no kids. Every day, he w¬akes up to a hearty breakfast prepared by his wife, YVONNE.
He arrives at the office and is greeted enthusiastically by his colleagues. This morning, he wanders around looking for his partner DUKE to inform him of a colleague’s bachelor party. He continues his search in the pantry and other places until he wanders into the toilet and he hears scuffling in the last stall. Thinking that something is amiss, he bursts the stall door open only to find Duke making out with his wife, STACEY. He stands motionless, blinking a couple of times before coming to his senses and turning away, but not before the image of Stacey’s bare, braless back imprints itself in his mind. Duke swears loudly and kicks the door close but it bounces back open to hit his outstretched hand and he gives an unnatural yelp of pain. Jon turns to look again. Duke grabs the door and locks it while Jon uses his hands to cover his eyes, feeling guilty but turned on at the same time.
Later, Duke confronts Jon about the “unintentional interruption”. Jon looks sheepish initially but turns the tables on Duke, questioning his lack of judgement for having a tryst in the toilet. Duke mutters something about excitement in public space. Jon saves him further embarrassment by asking him to attend the bachelor party and after persuasion, Duke agrees.
The bachelor party happens on a cruise with music, strippers and plenty of booze. Jon makes a rude speech about marriage and then announces that the strippers perform, one of whom dances up on Duke. Jon catches the look on Duke’s face as the stripper teases him but stops short of any real action. After a round of rapturous applause, Duke takes a seat beside Jon. In their half-drunken state, Jon teases Duke about his monogamy before casually suggesting that they “swop” wives for the night as “technically” would not be cheating – both of their wives would be getting laid. They laughed at the idea, calling it ludicrous before brushing it off.
Jon, Yvonne, Duke and Stacey spend a day at the beach. Both couples are having fun, chatting, sipping margaritas by a beach bar and they get up to play a game of beach volleyball. Yvonne spikes the ball hard in Duke’s face, to which he lets out an unnatural yelp of pain. Tasting iron, Duke dabs his wrist on his lower lip only to see a big splotch of blood. The women gasp while Duke, mumbling that everything was alright, grabs Jon into the toilet to wash up with him. Jon protests by calling Duke a weakling but follows him anyway.
Duke washes the blood from his mouth. He tells Jon that he has been thinking of his proposal about the “swop”, especially after being so distracted by Yvonne in her bikini, which was what caused him to get hit by the ball. Duke speaks funny because of his swelling lip, much to Jon’s amusement. Jon is taken by surprise at this sudden revelation but treads gently, knowing that this is his chance. They think about how to switch places without their wives knowing and start comparing their physique and whether they could pull it off. Finally they decide that they would go on a trip together to Bintan in a month while taking the time to prepare and plan so as to prevent their wives from knowing the difference.
Jon and Duke work out together. Jon cuts his hair shorter while Duke grows his longer. Jon even waxes his chest. However to their dismay Yvonne tells Jon that she is against going Bintan that weekend because of her period which would not allow her to enjoy being at the beach to the fullest. Jon and Duke panic as the they have applied for leave that weekend. Jon and Duke visit a Chinese sinseh who gives them a cocktail of herbs that make Yvonne’s period arrive early. Jon sneaks it into a soup that he claims to have “cooked”. It works and she agrees to go on the trip.
The evening before the trip, Jon sits down with Duke at his place and they plan how it should happen. They have booked semi-detached bungalows which are next to each other so that they can sneak into each other’s rooms at night. They are then forced to reveal their sexual habits to each other so as not to arouse the suspicions of their wives. Jon almost backs out when he hears some of Duke’s rather long list of things-to-do such as both of them sharing a mint before a session but Duke convinces Jon that it is not as difficult as it seems. Duke comes up with a list and makes Jon memorise it before he is convinced that he would not blow his cover. Jon, on the other hand, had a more straightforward routine. Duke criticised him for being boring and unromantic but Jon shot back by saying that he has always “hit his target” and that he would know the extent of Duke’s prowess should he get “complaints” the following morning. They then set their watches to the same time.
The next day, the happy foursome set out on their trip to Bintan. They enjoy the sun, sea and sand. They indulge in volleyball, they even managed to kayak, ride the ATV, go for full-body massages and to top it all off, enjoy a luxurious, romantic dinner separately by the beach.
Following that the both of them get their wives into bed. At 2AM sharply both of them get out of bed and exit the door silently. They signal thumbs up to each other, go down a short flight of steps to switch over when suddenly, Jon rushes back to his patio. Jon then points to the rather large monitor lizard at the bottom of the steps. Duke is about to throw Jon down the steps until Jon signals that he will climb across his patio to the Duke’s patio. He slips halfway and the sound causes Duke to slap his forehead in frustration.
Jon enters the room cautiously and snuggles up to Stacey. In a few moments, soft moans begin coming from the sheets.
Duke enters the room cautiously and snuggles up to Yvonne. Yvonne turns rather abruptly to face Duke and accidentally elbows his mouth to which he emits a muffled but unnatural yelp. Not knowing what to do he just lays there as still as a rock.
Yvonne leans in closer and in a dreamy voice, whispers in his ear that she knows it is him. She admits that she has fantasised about him. Then, she kisses him.
