"There are only 2 reasons for a boat to go rogue. One is to defect and the other is to start a war and I don't think we're defecting." This movie is based on actual evens set during the Cold War between the US and the USSR. After returning home and excited about being on leave the A Russian sub captain (Harris) and crew are stunned when they are chosen to go on another mission right away. The mission is classified and the only one on the sub that knows the details is a KGB agent Duchovny). When certain details emerge the crew starts to rethink the orders they are given. I was looking forward to seeing this for really one reason. I am a huge Ed Harris fan. He did not disappoint in this movie. The movie itself is also really good and the best way to describe it is a mix of Hunt For Red Octber and Crimson Tide. The fact that the movie is true makes it even more interesting to watch. It is a little predictable but that does not take away from the enjoyment of the movie at all. If you are a fan of movies like Red October then this movie is for you. I recommend this. Overall, very tense and exciting. I give it a B+.
