A popular writer from Warsaw, Franek Czułkowski, celebrates his 40th birthday with his friends and lots of stimulants, but reality hits because of his daughter's school problems.

Czuły forgets about his famous father’s art show after a lavish party; later that night, he decides to keep a lonely neighbor company, which doesn't end well.

Elka uses her contacts to get Czuły a job as a copywriter at an advertising agency; Franek, trying to make up time with his daughter, takes her to the countryside to visit her aunt Marzenka.

The relationship between Czuły and Zosia grows; after collecting an advance payment for the completed part of his book, Franek settles some of his obligations to his ex-wife and daughter; Uncle Teddy unexpectedly arrives in Warsaw from the U.S.

Czuły trains for a marathon to impress Zosia and show her how much she means to him; his friends have serious doubts about her.
