The one-minute-and-forty-seconds clip, titled "Vengeance," finds Arya Stark (Maisie Williams), Cersei Lannister (Lena Headey) and Daenerys Targaryen (Emilia Clarke) in their quest to avenge all those who have wronged them and their families in the past.
"The day will come when your joy will turn to ashes in your mouth," Cersei says at one point. "And you will know the debt is paid."
The video comes a week after HBO released a 15-minute feature showcasing a few details of what's to come in the show's upcoming season, and a month after the first teaser trailer for the new season was unveiled.
GOT returns to the small screen on April 6 at 9 p.m.
