The Lucullus prison consists of five underground floors, the first floor houses 300 prisoners, the second floor houses 100 prisoners, the third floor houses 50 prisoners, the fourth floor houses 10 prisoners, and the last floor, the lowest one, houses 3 prisoners including Jessie. All the prisoners are free but cannot get out because the exit is already closed by a giant steel door five meters thick and they are trying to get out. Other prison officers are also trapped and some are killed.
