Plot: A descent into Hell is triggered when "Ex-Lord" Donald Brocklebank finds that he must leave Longleigh House for London to find a way to pay for the medical treatments for his wife Nancy. Alone, his over-protected, delusional, adult son, James, fancies himself in charge of the manor house with his terminally ill mother, and barricades the two of them into the house for a series of ever more panicked home treatments, mistakenly protecting her from the arrival of Nurse Mary and any outside help.
