The story here is a very basic one of infidelity, a married man gets together with another woman while away on a volunteer fire-service training weekend, nothing very exceptional happens as the predictable story unfolds. It's the way the story is told that's interesting, the presentation is very real, a soap opera would feel the need for drama and histrionics, other films might build tension or stress. Here there's a lot of space, the dialogue is sparse and there's no music filling in the gaps. The tragedy of normal life is left room to come through in a very natural way.
The film seems to draw heavily on the Dogme 95 techniques without going to that extreme. The actors aren't professional, but do a superb job of conveying emotion with few words.
