Nadya Chudova, a graduate of the Moscow Medical Academy, decides to work in a provincial hospital in her hometown after graduating, where she was once saved by a talented surgeon, Andrei Krylov. Nadya gives the impression of being an eccentric, but in fact has a unique gift for seeing illness with the help of synesthesia, a neurological phenomenon that appeared after an accident she experienced in her youth. Although her unusual abilities help her in her work, they cause irony and ridicule among those around her.
