Into a Vault

With three joined up holes, the gap is about half a meter wide and 25 centimeters high. But first they need to push the cabinet away from the wall so they can get into the vault. The sound of creaking metal intensifies as pressure builds on the pump handle. With each compression of the pump, reader looks expectantly into the hole. Then a loud crack and a deafening hiss fills the room. For a moment, the room is silent, then perkins erupts: Jesus christ. What are we going to do now?
