You are the experiment.

Norma and Arthur Lewis, a suburban couple with a young child, receive a simple wooden box as a gift, which bears fatal and irrevocable consequences. A mysterious stranger delivers the message that the box promises to bestow upon its owner $1 million with the press of a button. However pressing this button will simultaneously cause the death of another human being somewhere in the world; someone they don't know. With just 24 hours to have the box in their possession, Norma and Arthur find themselves in the cross-hairs of a startling moral dilemma and must face the true nature of their humanity.
The Box keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder, compressing morality, choice, greed, authority.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
Other films that change a standing rule of their world — ranked first by those bending it at the same rung.
