At three o'clock in the morning, delivery boy Lin Zhou received a high-priced order, but the address was 404, Xingfu Community, which burned down ten years ago.

Every order is a strange story; every delivery brings out an old case.
Until Lin Zhou discovered that all the orders were leading him back to the fire ten years ago.
