Poor theater actor Lee Soo-hyun.He fainted after being hit by a falling light, and when he opened his eyes, he possessed a character in “The Blue Knight of the Holy Sword”, a novel that was discontinued due to unpopularity.What’s more, he transmigrated into the body of Arendt von Eckhart, who betrayed the Knights Templar and was destined to be executed soon.The only thing left for the character who has completed his or her role on stage is to exit. In other words, there is only death… Character interpretation can vary depending on the actor playing it.“Please take care of me, you traitorous bastard.”In order to survive, he must create a role other than that of Arendt, the ‘traitor’, even if it means twisting the story.Now, the life-threatening method acting begins!
