Děvčátko, neříkej ne!

In a discussion among film makers about the critical state of the film industry and about the discord between audiences and critics, the title of a new film is surprisingly born "Don't say no, girl". The film will definitely be fun... On the strength of an anonymous letter alleging infidelity on the part of his fiancée Margot, the industrialist Hora hires Pejsek the detective. The latter's investigations reveal Margot's attempt to get money from Hora for her lover Pepito, a cheat at cards and crook. Pepito has blown twenty thousand crowns in a game of cards and has to pay up by midnight. At a fashion show Hora gives Margot a cheque so she can buy a fur coat but by accident she leaves it in the coat pocket. Eva, a sales girl and model, secretly borrows the fur coat after the show. Eva then meets the factory owner Hora who has managed to win her affections even though he is pretending to be a chauffeur. The long hunt for the fur coat and the cheque ends at the police station. A morning confrontation resolves everything: Margot gets the cheque and fur coat as indemnity from Hora, and Hora gets the model Eva. (official distributor synopsis)
