Guan Dawei (played by Wang Ning) is a young man who grew up in a village in the city. After graduation, he went to a big city to work hard, but in the end he chose to stay in his hometown and live the most ordinary life by collecting rent. His childhood sweetheart Tang Ziran (played by Shi Yufei) became an enviable flight attendant with her beautiful appearance, so the intersection of their life trajectories became less and less... One Sunday morning, Guan Dawei woke up and found himself in a magical time and space loop. In this wonderful cycle, Guan Dawei got a huge fortune and completely got addicted to being a local tyrant. While he was "living freely", his first love girlfriend Tang Ziran was caught in a sudden air crash crisis. Guan Dawei suddenly discovered that only by entering the time and space loop could he help Tang Ziran get rid of the crisis and save the lives of everyone on the plane. Is it to choose "living freely" and "continue to enjoy", or to sacrifice the self and save everyone. For the coming tomorrow, where should Guan Dawei go at this time?
