We will first present a simple neutral scene that is based on a suggestion from the audience. Then we will see a series of scenes that led up to or were consequences of the first scene you saw.
The first scene must establish some strong characters. Following the first scene the host will start to call out time references: five minutes ago, ten years from now. Each call out from the host is a signal for a new scene. Each scene will somehow be connected to the initial scene, through either characters, location or consequences.
Call out zero seconds from now, or 5 million years in the past.
