The Riddle of Riemann

The film follows businessman Sergei Andronov and his housekeeper, who are shot dead in their apartment. Andronov's younger brother, Andrey, an autistic and brilliant mathematician, may have witnessed the crime while in another room. He communicates with investigator Olga Barkovskaya through mathematical formulas, adding a unique layer to the investigation.

As the plot unfolds, suspicion falls on several characters, including Andrey himself, Albin, the wife of the murdered businessman, Ilya Riman, a former friend, and Stukalov, the husband of the murdered housekeeper. This intertwining of personal relationships and mathematical intrigue creates a compelling narrative that appeals to fans of dramatic storytelling.
