She informs her manager, Ozeran, who initially laughs it off, but when he learns the passport was in the jacket, he becomes serious and involves the tour director, Grigory Stepanovich, in the search.
What follows is a comedic sequence where Misha, reveling in his role, “interrogates” members of the touring group, uncovering personal dramas and minor scandals.
Through the process, they learn that Ozeran is traveling on a falsified business permit to secretly visit his opera singer lover in Leningrad, and Grigory Stepanovich, despite his credentials, reveals himself as a petty schemer who owes his position to drinking sessions with superiors.
As the faux investigation unfolds, Misha declares everyone a potential suspect, while Pyotr, guided by his principles, reminds him about the presumption of innocence and the risks of jumping to conclusions.
