Kala (1958)

There are two stories in this movie. One treats the human side, the things happening to a man in a war, the pain and pressure on his nerves and courage and how he copes with everything in order for him to survive and not lose his sanity. The other story deals with the animal side, the things happening to a dog who gradually loses everything he knew and loved and is even faced with a threat to its existence itself. To survive the dog has to forget everything it was taught and hold dear, fear the man and its tricks and become wild and free again.
