A man refuses all assistance from his daughter as he ages. As he tries to make sense of his changing circumstances, he begins to doubt his loved ones, his own mind and even the fabric of his reality.

Having scared off his latest caregiver, Anthony, an ailing octogenarian Londoner gradually succumbing to dementia, feels abandoned when his concerned daughter, Anne, tells him she's moving to Paris. Confused and upset, debilitated by his rapid mental decline and warped perspective, Anthony loses his grip on reality as he struggles to navigate the opaque landscape of the present and past.

As a result, fading memories and glimpses of lucidity trigger sudden mood swings, distorting Anthony's surroundings, loved ones, and even time. But why has his younger daughter stopped visiting? And who are the strangers that burst in on Anthony?
