A gaggle of enticing younger folks (in fact) awaken to seek out themselves prisoners in a mysterious home with no technique of escape. They’re every outfitted with new accouterments–electronic units hooked up to the bottom of their skulls–and a recording on a tv display alerts them of their job. As a way to escape, they need to harm themselves and one another. The chemical substances that the mind produces when in ache are collected by the units, and when it collects a predetermined quantity, the doorways shall be opened. Fail to do it in time, and all people dies.
