It's been ten years since the last rain. Oregon looks like the Nevada desert. A teenaged-girl and her crippled friend live in the attic of an abandoned looking house so they aren't bothered by human predators. During the day she goes out and scavenges parts because they have an airplane that needs only one part to work--and they presumably want to go out to another area where there's more water. They do get their water from a well, as do the other weary looking people in the area. Then, strangers come in and they execute people if they don't join their group. The leader, Carson (John Gries) says he's doing this for his bratty daughter, who is also a killer. The movie goes on and on like this--then, when her roommate is brutally shot the girl flips out, gets a long sword, and becomes this samurai-like vengeance machine that made me laugh out loud a couple of times.
I think my biggest problem with this film is the casting of Haley Lu Richardson as the girl, Kendal. I did not believe her in this role for a minute. Also, the story doesn't add anything new to the "end of the world" genre of movies. Instead of this watch any of the MAD MAX movies. They are a million times better.
