A man practicing sword fighting in a field with horses.

The ad opens with a man in a field, seemingly practicing with a sword near a tree and horses. It quickly cuts to a close-up of a young man holding a sword, then to two figures on horseback carrying banners with a dragon emblem. The title card appears, stating 'A TALE 100 YEARS BEFORE GAME OF THRONES'. We then see a group of people gathered around a fire, followed by a young man in a dimly lit room. A knight in armor on horseback rides through a misty landscape. The ad concludes with the title card and HBO Max branding.
