The film begins in September 2008 (opening against the backdrop of news of the Islamabad Marriott Hotel bombing) with an elderly Lady Thatcher buying milk unrecognized by other customers and walking back from the shop alone. Over the course of three days, we see her struggle with dementia and with the lack of power that comes with old age, while looking back on defining moments of her personal and professional life, on which she reminisces with her (now-dead) husband, Denis Thatcher, whose death she is unable to fully accept.
