Margarita, in her sixties, lives almost alone. The past seems settled until Demosthenes reappears in her life – the man who marked her entire adult journey.

He asks her to stand by him through a difficult path: he has been diagnosed with Alzheimer's. To hold on to his memory, he writes. Notes, thoughts, small stories of his life. He entrusts them to her.

Through these pages, their shared past unfolds: the moments that united them, the silences that separated them, the people and events that marked them.

Margarita reads and remembers. She confronts again what she lived – and what was never said.

Now she must decide:

will she keep him close until the end?

And will Demosthenes' salutation "Dear Margarita" ever change?
