A woman bursts into Rylov's apartment, fleeing a maniac killer. She learns from Nikolai that his wife has been in prison for a week, says that she would like to cheat on her husband, and invites Rylov to dance. While dancing, she stumbles, falls and dies. Similarly, by chance, deputy Selyodkin, who visited Marya Gavrilovna to offer her to marry him, and Dasha's friend, Arab Abdullah, die. Under the leadership of Marya Gavrilovna, the Rylov family gets rid of the corpses, but Felix Valeryevich Merzotin, the Rylovs' neighbor with disgusting habits and an abnormally large right ear, who guesses about the deaths, does not let things get hushed up just like that.
