Delivery boy Chen Shi has acquired a strange ability: every time he takes an order, he can predict the customer's death in the next 24 hours. After trying to save an old man living alone, he was trapped on the same day. Only by saving all those who are predicted to die can the cycle be broken. From then on, he rode a little electric donkey and ran around in the never-ending day - stopping car accidents, solving murder cases, and catching every falling soul. Until he met Shen Qingyin, a psychological counselor who committed suicide many times. Through thousands of repeated encounters, he gradually understood that he was not only saving others, but also himself who was trapped in the past and numbly delivering takeaways. This is a race against time for redemption. The end point is tomorrow, or is it her?
