Berserkers

A warrior in a helmet and armor stands in a mountainous landscape, then the scene shifts to a man with a bloodied face and matted hair, who looks down and then up with a grim expression. The sequence cuts to a bearded man in a dark, red-tinted scene holding a curved blade, followed by a close-up of a man's face in profile, and ends with a warrior in armor and a shield standing in a hazy, outdoor setting.
