A married couple are driving on their way to a marina for a weekend on their small yacht when a young hitchhiker steps in front of their car. The husband berates the young man but lets him ride anyway. At the marina, the husband invites the hitchhiker along, provided he helps get the boat ready for sailing. The hitchhiker somewhat reluctantly joins them, but as he helps out, the husband toys with him, playing little games of one-up masculinity with taunts flying back and forth that create a tense mood which the wife tries to ignore, although she does seem intrigued by the handsome young hitchhiker. Listening to a boxing match on the radio makes their competition more literal: a race to see who can blow up a mattress first, a game of pick-up-sticks. Eventually, the two men play the knife game, in which one person spreads the fingers of their hand on a surface while the other person jabs a knife (in this case, the hitchhiker's switchblade) quickly between the fingers, trying not to hit flesh. The knife becomes important both symbolically (one of the most obvious phallic symbols in 60s movies, next to the nuclear bomb that Slim Pickens rides in Dr. Strangelove) and literally. Finally, in the middle of the night, the men wind up fighting on deck and the boy, who says he can't swim, falls in the water and vanishes. Is he dead? Somehow in hiding? And what will the couple do now?
This was Roman Polanski's first film and still one of his best—I'm not a big fan except for Chinatown and Rosemary’s Baby. It holds up surprisingly well; this could easily be passed off as the recent work of an indie director. The black and white cinematography is crisp, the small setting only feels claustrophobic when Polanski wants it to, and the acting is fine. This was the first film for Jolanta Umecka (the wife) and Zygmunt Malanowicz (the boy, pictured) and they are both excellent. Leon Niemczyk as the husband is a bit less effective, perhaps because his role as the older man whose masculine reputation is in danger is mostly on the surface, whereas the personalities of the wife and the hitchhiker both remain a bit ambiguous, with more interesting character shadings present, even if they don't come to full fruition. This is a movie in which violence is always a possibility, even if it rarely occurs, and I can see a viewer being a bit disappointed in the ending, which, while not ambiguous in terms of plot, does leave the situation of the husband and his wife wide open (though the wife seems to be on the boy's side, she also compares him to the husband, saying he is "half his age and twice as dumb"). But for me, that's one more reason why this film still works so well. [Criterion Channel]
