Lin Du transmigrates into a prison where everyone's memories are wiped every thirty days.
Everyone forgets who they are. Only he remembers everything.
Using prophetic dreams to avoid every deadly trap in advance, he turns his information advantage against the prison bullies, the warden, and the mastermind behind it all, taking them down one by one.
Before the Tidefall begins on the thirtieth day, he must lead the prisoners of Sector Twelve out through the drainage tunnels.
