Thank God You’re Here is based on a simple premise: get a group of well-known performers and make each walk through a door into a scene without any idea of who they are or what they’re walking into.
The only things they can depend on are their abilities to make everything up for the next five minutes and cover their tracks as they do it. There’s no getting voted out and it showcases a performer’s versatility as well as their abilities to lie, deceive and… well… basically bull@#*t!
