Autumn, 1907. When a depressed Hungarian Countess is found drowned in the bath of her lavish hotel suite, it looks like suicide.
Intense scrutiny falls on her psychoanalyst, Max Liebermann, who asked the Countess to stop taking her prescribed medicine and start taking a course of Freud’s talking cure with himself.
Investigating Officer Oskar Rheinhardt teams up with the disgraced doctor to solve the riddle of the Countess’ death and clear Max’s professional reputation.
A post-mortem reveals that the Countess was poisoned, which turns Max and Oskar’s attention to Oktav Hauke, a young Second Lieutenant with a reputation for dubious relationships with rich, older women.
When Max’s private practice is vandalised and transcripts of his meetings with the Countess are stolen, it seems that Max knows more than he realises.
Max searches for clues to the identity of the murderer, but it will take more than understanding the source of the Countess’ melancholic dreams to unlock this case.
