Each episode involves performers walking through a door into an unknown situation, greeted by the line "Thank God you're here!". They then had to improvise their way through the scene. At the end of each episode a winner was announced.
Sam Pang, Urzila Carlson, Guy Montgomery, Anisa Nandaula & Hamish Blake, step through the blue door for the last time this series, on Thank God You're Here.
