When Zhou Ming woke up for the seventh time, he was finally convinced that he was trapped on April 26. Every day, the same birds chirping outside the window, colleagues repeating the same greetings, and the news broadcasting the same content. He tried to change, but at 6:30 the next morning, everything would reset precisely. It wasn't until the seventh day that he discovered the car accident that happened on time every day, as well as the strange symbol on the light pole at the scene of the car accident that shouldn't exist and was reflected on his ceiling. In order to end this endless imprisonment, he must drag his only friend together to find out the truth about the disappearance of the woman in the gaps of the cycle tonight.
