Hidden Talents (1986)

Nellie (Pat Phoenix) is weak and bedridden in her aging, decrepit house due to a bad heart. Living out of her front room, Nellie is looked after by her son Harold (Tom Bell) who is going deaf and prone to eccentric and emotional outbursts following a motorbike accident some years previous. Relations are tense and fractious between Nellie and Harold, a state of affairs which isn't helped by Nellie's affectionate recollections of her estranged son Stanley (Tom Georgeson) who left many years before, taking with him Nellie's savings.
