Jennifer comes home from school feeling blue because after choosing the American classic ""Huckleberry Finn"" as the subject of her book report, she learns that the novel has been put on the school board's list of banned books. Although her favorite English teacher, Mr. Flaherty, disagrees with the decision, he informs Jennifer that he must uphold the board's ruling about the book.

Jennifer decides to disregard the school's edicts and goes ahead with her report, which she insists of reading aloud in class. Flaherty is forced to summon the principal, who confiscates the paper. Later, Flaherty tells Jennifer and her family that even though he personally admires her courage and commitment, he must fail her on her report. Even worse, she must face the wrath of the principal and possible suspension.

While Jennifer steels herself for a showdown with school authorities, Steven and Elyse prepare to back her up in her fight against the school board's book banning policy. Even Mallory gets into the act and shocks the family by falling in love with the forbidden ""Huckleberry Finn"", which she ends up reading aloud to Nick.

Nothing is solved at the meeting with the school principal, Dr. Hewitt, the head of the school board and Jennifer's English teacher Mr. Flaherty when the Keaton's refuse to comply with the new school ruling. Jennifer is crushed by the fact that Flaherty, whom she respects and admires, will not stand up to Hewitt and the board even though he claims to be completely on her side.

Pushed to a more serious confrontation, Steven and Elyse hire a lawyer to challenge the School Board decision, while Jennifer fields calls from reporters and grows increasingly uneasy with her notoriety. When the final face-off comes, Jennifer makes an impassioned plea for the freedoms of speech
