The former God of War in the North, in order to pursue the conspiracy and protect his old love, he became the most ordinary courier in the city incognito. When he decided to stop pretending and regain everything, he was assassinated. When he opened his eyes again, he returned to seven days ago and fell into an inescapable time loop. During these seven days of reset, he must use his humblest identity, on the most familiar streets, to complete two impossible tasks in countless "reappearances of yesterday": to uncover the international killer organization lurking in the shadows, and to make the woman who has left heartbroken fall in love with him again. This is a counterattack against time, and also a road to chase his wife across the cycle of life and death. When the dawn of the seventh day finally stops resetting, the last "delivery" he sends will be all his sincerity and a grand reunion that has been delayed for many years.
