This improv game is in the following improv game categories:
On stage actors "pop up" from a lying position as a narrator tells the story, or introduces the next scene. The narrator may "pull the tab" or "turn the wheel" to put some action in the page. Justification should be placed on both the narrator and the pop-up actors at various times throughout the story.
You can either have the whole story "told" by the narrator, or use the flip-of-the-page as your Edit mechanism. In the latter case, once the whole scene has popped-up, a player may start playing, talking, walking around.
Remember that players may as well pop up as props; this may be a good way to do some Object Work.
