Our anti-hero bachelor Robert as makes his way through a series of encounters with April (the stewardess), Kathy (the girl who's going to marry someone else), Marta (the "peculiar" one), as well as with his married friends. 

On the night of his 35th birthday, confirmed bachelor Robert contemplates his unmarried state. In vignette after hilarious vignette, we are introduced to "those good and crazy people," his married friends, as Robert weighs the pros and cons of married life. In the end, he realizes being alone is "alone, not alive."
