Symbolic. The story of how buffalo escape from slaughter house and how the people kill it in the end. But that is just superficial side of movie. Think the buffalo as a target/final goal/ some ego nourisher and the folks running behind it as us who chase it wildly to prove ourselves to other folks. The obvious rat race. The human story but very very symbolic and beautifully directed. You will enjoy it. Dig deeper into this movie. It is not just a buffalo chase. It our chase in life to prove ourselves.
