Přítel lhář(1957)

Kamil and Vlasta are a married couple living apart for work. When Vlasta stops in Prague to surprise him, she finds him “away” and asks his friend Pepek for help. Ignoring Pepek’s excuse, she heads to a nightclub—only to encounter Kamil with his mistress. News of Vlasta’s visit forces Kamil into a charade: he returns home to her empty-handed, then avoids her until morning at the station, where a mysterious package brings his clandestine night to a close.
