Realistic Nordic snowy night. A man runs fast through deep snow, tracked closely from behind at foot level. A wolf chases him, maintaining a strong sense of speed. The man trips and rolls; the wolf lunges at him. A border collie jumps in, knocking the wolf aside. The animals wrestle; the wolf breaks free and howls. Multiple wolves slowly surround the man and dog. Close-up on the dog as the owner slowly sits up. Background music: tense and evolving with the action.
