But the warden yields to temptation and conspires to keep her in the most thorough form of restraint - the yoke. Designed to be temporarily worn by bellicose inmates until tempers cool, Jennifer finds herself wearing it constantly. To make matters worse, extensions are arbitrarily added to her sentence for various non-existent infractions.
