Under Quiet Neath

Ever had a client you were dying to get rid of? (One who was obviously bursting for the bathroom?) Is your boss the boss from hell? And is there some government bureaucrat out there who you only tolerate because you absolutely, positively, need the money?
Some people imagine hell as being underground, and today, Janice can see why. Hers is probably the most secure office in town, impossible to break into. In order to protect client confidentiality, Janice's assistant Nia locked the door, for the last meeting before Christmas.
Unfortunately, the key broke, and soon there is no one on this sleepy South Wales industrial estate to help them out.
Now Janice, Mason, Nia and Rhiannon must work together to find a way out, before they die of thirst. If they don't kill each other first.
A play for four actors, (and some offstage or recorded voices.)
