This set includes Night Watch [Unrated] and Day Watch [Unrated], the first and second installments of the Russian horror/sci-fi trilogy about an ancient war between the forces of light and darkness that continues in contemporary Moscow.
If you are into horror/sci-fi vampire movies Night Watch and it's sequel Day Watch is a good pairing. You get 2 movies at a great price and won't be disappointed.
The movie follows closely to the short story "Story of Your Life" by Ted Chiang. If you are into Sci-fi great movie to pick up. Haunting and thought-provoking.
