I'll try to answer you the best I can. Levels are made of many maps connected between eachother by area portals (they look exaclty like doors but instead of opening they load the map they are connected to) so if you want to look at the rest of the whole level there must be another .map file in the folder you found the "prison" one. If theres no more .map files then the custom story you downloaded is probally not finished like most of them at this moment. Please make me know if thats not clear enough I'll do my best to explain. English isn't my first language so my explanations may be cheesy.
