THE LETTER FOR THE KING centers on 15-year-old Tiuri (Amir Wilson), the stepson of a Dagonaut knight whose high hopes for his adopted son following in his footsteps go mostly unfulfilled. Despite all the best training, Tiuri's destiny as a knight isn't promising, and his gentle nature doesn't ingratiate him to his peers competing to earn the title, either. But when fate steps in and sweeps Tiuri off on a dangerous quest to deliver a secret letter given to him by a dying knight in the hopes of saving the kingdoms from a looming darkness wrought by the bloodthirsty Prince Viridian (Gijs Blom), this unlikely hero's true destiny begins to take shape. As he races across the land on the magnificent and intuitive steed Ardanwen, he makes allies and enemies along the way and slowly confronts the truth about who he is and where his destiny will take him.
