Aidan Bloom is a 35-year-old father of two struggling to be an actor in Los Angeles while his wife, Sarah, works a tedious data entry job. In order to send their kids, Tucker and Grace, to a Jewish school, they rely on help from Aidan's father, Gabe, who insisted they go to an Orthodox Jewish day school.

When Gabe reveals his cancer has returned, he tells Aidan that he has decided to put the rest of his money into a new stem cell treatment, meaning his grandchildren can no longer afford to attend their school. After school administrator Rabbi Twersky refuses to provide any aid to the Blooms, Sarah suggests that Aidan homeschool their kids, and their adventure of self-discovery begins. Through teaching them about life his way, Aidan gradually discovers some of the parts of himself he could not find.
