Tram driver Marie (Jirina Bohdalová) has far too much to do after her shift is over. But she likes to do it all since she loves her husband Václav (Radoslav Brzobohatý) sincerely. One day she spots him on the Lesser Town Square in Prague, kissing an attractive blonde good-bye. It seems to Marie that her small comfortable world has collapsed and she walks out of the tram in tears. But her sadness does not last long. She wipes off the tears and begins to act. She withdraws all the money from their savings books and buys off all the latest models from the Fashion Works. The visit to the beauty salon then completes her transformation into a lady.
