((Fabric wouldn't show signs of electrocution))
You find yourself in a simple white cell, waterproof metal. There's one door, a computer, and a bed. Also, a toilet. Fairly accomodating, for a prison, and from what you can see, you would be able to simply slip through the cracks between the door and the floor. However, there is quite often more to a cell than can be seen, and it cannot be doubted that there'll be some form of security system.
