The original story of the new "Seven Deadly Sins" movie is written by Suzuki Osamu, the creator of the TV series of the same name. The trajectory of "Seven Deadly Sins" and "Four Horsemen of the Apocalypse" overlaps to start a new story. 14 years ago, the Kingdom of Liones defeated the demons and the world has been at peace since then. Now, Prince Tristan is helpless in the face of two uncontrollable powerful forces: the demons led by his father, the leader of the Seven Deadly Sins, "Sin of Wrath" Meliodas, and the goddesses led by his mother Elizabeth. Elizabeth's life is threatened, but Tristan flees to Edinburgh and seeks refuge with Despias, who was once one of the Paladins of the "Six Stars of the Sky" of the Kingdom of Liones. But what is Despias's motive? The wheel of fate begins to turn, and even the Seven Deadly Sins are not immune.
