It`s about the anti-Semitism of prosperous post-war America and the insidious way jews were excluded from high-level social clubs, resorts, and, of course, jobs. There have been no official bans, only a nod and wink and a «gentleman`s agreement» between non-Jews of conservative wasps that they know the kind of people they want to be associated with. This is the kind of everyday prejudice that Groucho Marx elegantly retaliated with his joke that he didn`t want to join a club that would have him as a member. Finally, after many discussions with his older and worried mother (an Anne Revere Typecast), Phil has a Eureka moment. Of course! That`s all! Just as he wrote Orwellen reports about being a minor or Okie — he would be Jewish! He pretended to be a Jew and applied for jobs, associations, hotel reservations, etc. In a state of literary ecstasy, he almost shouts, «And I have a title for that – I was Jewish for six months!» Philip Schuyler Green, a widowed journalist, comes to New York city with his son Tommy and his mother from California to work for Smith`s Weekly, a leading national magazine. John Minify, the publisher, wants Phil to write a series about anti-Semitism, but Phil is lukewarm on the order. At a party, Phil Minify`s niece meets Kathy Lacy, a divorcee attracted to Phil, and Kathy reminds her uncle that she proposed the series some time ago. Tommy asks his father about anti-Semitism, and when Phil struggles to explain it, he decides to accept the mission. However, he is frustrated by his inability to find a satisfying approach, as he and Minify want the series to go beyond simply discovering the «crackpot» mentality. After trying to imagine what his Jewish childhood friend Dave Goldman, now in the military abroad, must feel when he experiences bigotry, Phil decides to write from a Jewish perspective.
However, he continues to struggle to write until he realizes that certain things can never be known until they are experienced first-hand, and that the only way to have the necessary experience is to appear Jewish in the eyes of other people. . . .
