Two girls walk on the beach then make out and have sex. One of them is married to a guy, then the other girl shows up at their house. Then suddenly we get to hear the guy reading Don Quixote. They get drunk, they dance, make out. The next day they have to make tough decisions about the future. Either this takes place during a vacation or before a vacation because the couple is supposed to board a cruise ship the next day. The resolution of course is pretty expected.
Things tend to go wrong when Latin cinema gets all artsy. And by golly this movie tests the audience's patience. The first scene is of a cargo boat moving across the screen, in slo-mo. It's about 15 minutes into the movie when someone finally has something to say--3 or 4 lines maybe. The camera spends hours on something--food on a table, a white/empty painting on a wall. When the three drink and talk, we hear a camera reel spinning instead. I think there are 4 instances of someone talking for a minute or so, mainly the guy. 99% of the movie takes place without anyone saying anything. Music can get pretty weird when there is any.
The girls are attractive. Cinematography is nice. The movie is short, the end credits are ridiculously long for such a bare-bones movie. There's an after-credits scene which should have come before. It's worth watching for the girls, while you are doing something else and the movie is in the background since it doesn't require and thought, attention, or interpretation.
