Scarred Hearts is inspired by Romanian author Max Blecher's novel, which is set in 1937. It centers on Emanuel, a man in his early 20s, who spends his days at a sanatorium on the Black Sea coast, suffering from bone tuberculosis. Falling in love with another patient, he narrates his and his fellow patients' attempts to live life to the full as their bodies slowly wither but their minds refuse to give in. Blecher wrote the text, hailed as a masterpiece on publication in Romania in 1939, as autobiographical notes before he died, after 10 years of suffering, at the age of 29.
A couple of weeks after his wife Ioana dies in a car crash, drunk and alone on the night he turns 42, Alexandru receives a visit. Sebastian, a shy, younger man, has been Ioana's lover for the past five months. Sebastian has an outrageous request: he wants Alexandru to help him overcome the despair caused by Ioana's death.
