This is a generic escape movie with a supposed Cambodia setting, honestly this film was a dull experience and besides the irritating main characters and decent effects this film demonstrates why people who have no idea what other cultures and their politics are like shouldn't make movies, as well as end the entire black and white between rebels and authority instead of depicting both as evil.
Wouldn't recommend it what's so ever, instead watch the tunnel, Rec, or even quarantine which are far better movies involving escaping a dangerous threat.
