Story is a game in which one performer plays an author, narrating the non-speaking parts of a story with an audience-suggested title. The other three performers portray the characters in the story, entering when prompted by the narration, and making up dialogue. The author works towards an audience-suggested moral of the story.
In the Green Screen and Improv-A-Ganza versions, instead of a narrator one performer is the leader. As the leader points to the other performers, they must take over telling the story from where the last performer stopped.
