A man sees the back of a nude woman standing in a pond in a forest at night when a snake swimming towards her. He jumps in the water to save her from it, swimming up to her and grabbing the snake just before it gets to her. She dives into the water and the man discovers that the snake has turned into a stick in his hand. A little girl later tells him that she wasn't a woman, she's a fish.
