The exposition is a barbaric king ruled, held trials of law by chance in a grand arena. The accused either chose the door with the tiger, or the door with the maiden.
The rising action is every event leading up to the fateful opening of the door. The king builds an arena, “an agent of poetic justice,” where the accused will either be eaten by a tiger or marry a maiden, depending on which door he chooses.
The climax of the story comes when the young lover in the arena goes to the door indicated by the princess and opens it.
The falling action of the story is actually the point at which the princess waves her hand to the right and the story ends.
There is no resolution, the ending you choose really what you think happened at the end.
The central idea/theme is choices and consequences. because in the story he has to choose between two identical doors, one of which has a vicious tiger and the other a fair lady.
