It is about the friendship between a Modern Orthodox Jew named Reuven Malter, and a Hasidic Jew named Danny Saunders. Reuven's family sees observant Judaism as being compatible with being part of the secular world around them; they also are Zionists. Danny's family sees the tendencies of the secular world around them as being incompatible with living a traditional Jewish life, and they believe that Zionism, the attempt by Jews to create a state of their own, is not legitimate without the arrival of the messiah. Despite these differences, Danny an Reuven form a friendship.
Danny Saunders has problems related to his father, Reb Saunders, who is a Hasidic rabbi. The father expects his son to succeed him as a rabbi, yet Danny wants to go into psychology, a secular, non-religious profession.
The Chosen was made into a movie in 1981.
