Mira has managed to escape her cell during a (presumably very rubbery) riot. 
All she needs to do is to hit the emergency elevator button, and she'll be home free - it'll have her free, able to escape by using the prison warden's backroom. 

...or maybe she's about to hit the wrong button and end up in a MAX-SEC vault.
...or maybe this isn't even Mira, and poor Mira is still busy being enjoyed by the guards and other prison bullies. 

One thing's for sure - it's now or never for our anonymous MAX-SEC prisoner!
