Heartbeat is great movie made in United States. I do not watch many movies under the Thriller category, but this was great and now I am bigger fan of movies of this kind. Before you read this review and before I spoil you the story, watch the movie, I highly recommend it. It wasn't easy to leave the cinema, when I saw it first time. This movie is different, thanks to director. Praise him for it. Feel free to play the movie online or download it to your computer.
