It is set in a forested river area that doesn't show up in many International films. Andrejs is a wilderness guide, and his job is to guide a small group of people who are intending to film for a commercial on a vegetarian sausage. For them the trip is a lark, and they have little interest in safety or the dangers and soon they disappear. However Andrejs is serious about his job, and he tries to find out what happened. And it seems the forest has other ideas. And in this movie the forest really is the star. But it really comes down to whether the viewer cares as much as Andrejs does. There is a strange flower growing in the forest, which may explain some of what is happening.
