In the Western Desert, at a centuries old meteor crater, two men in a car discover a tree that has sprung up over night, and learn that the tree is different from any other tree on Earth and that it must have came with the meteor centuries ago, and it must be from another world. Just then, the tree sprouts arms and has a face, and it knocks the two men aside and begins drinking the water from their car. It then makes its' way to a suburban community, and drinks the water out of a swimming pool. It also drinks the water out of a duck pond and a factory water tank. With each water consumption the Tree Man continues to grow in size, becoming a giant monster.
