Viola Tarakanova ends up in the house of a murdered businessman, where she is accused of killing a blackmailer. At the crime scene, the body of an old woman is found near Viola’s feet—she holds the weapon of the crime in her hand, and a shot has just been fired. However, Viola insists that she didn’t shoot and had no motive to kill anyone. It’s strange that items belonging to Viola appeared in the house, though they hadn’t been there before.
