水中刀

一对中产夫妻驾车出游，丈夫（里昂•尼梅兹科 Leon Niemczyk 饰）总是夸夸其谈，但妻子（乔兰塔•乌梅卡 Jolanta Umecka 饰）只是随声附和。途中，他们遇到了一个临时搭便车的年轻人（兹古蒙特•马拉诺维兹奇 Zygmunt Malanowicz 饰）。夫妻经过商量，决定载他一程。三人来到了海边，丈夫准备用私家的帆船出海，为了向年轻人炫耀，所以邀他一同游玩。年轻人欣然应允，于是他们共同踏上了航程。 　　航行中，年轻人渐渐对他们敞开了心扉，三个人还玩起了桌面上的竹签游戏。年轻人对夫妻坦言，自己不会游泳，因此他只是孤零零地在甲板上把玩手中的匕首。丈夫跟他开玩笑，无意中却把匕首丢入了大海。年轻人很生气，结果两人厮打在一起，双双落入水中，妻子大惊失措，三人关系也因此发生了逆转……Well off Andrzej and Krystyna's marriage is at a stage where familiarity breeds contempt, that contempt which is outwardly shown only behind closed doors and only when an incident of some sort sets off one or the other. While driving through the countryside on a Sunday on their way to the lake to embark on an overnight sailing excursion, they almost run over a young male hitchhiker. Despite the antagonism between Andrzej and the hitchhiker, Andrzej offers him a ride as far as the marina. By the time they reach the lake, their antagonism has dissipated enough that Andrzej asks if he would like to join them on their sailing trip. The hitchhiker accepts despite knowing nothing about sailing. As the sailing trip progresses, the antagonism between the two men begins to increase again, fueled on both sides as each strives to be the alpha male. Andrzej needs to show his superiority, while the hitchhiker needs to show that his young age and inexperience, not only with sailing but with life in general, do not make him any less of a man in comparison. Later incidents demonstrate that their relationship may have been different if Krystyna was not in the picture. The hitchhiker's pocket knife, seemingly his most prized possession on his person, becomes a symbol of that power struggle between the two men. If the three emerge from their sailing trip alive, they may be forever changed by their encounter.
