There is a prison from which, it is said, no one attempts to escape. The reason is that the prison is guarded by Iron Lizards - self-propelled bombs which pursue people anywhere, based on data stored in a computer, and then finishes them off. Lupin and company learn that Fujiko is inside - held by the warden - and get inside themselves, but find themselves targets of the Iron Lizards. How will the breakout of death end?!
