Trouble brews when a widowed, small town librarian takes a stand against censorship. The trouble begins when the town fathers ask that she remove a book from the shelf because they deem it a pro-communist tract and fear it will taint susceptible young minds. She sees the idiocy of their request and defies them. They in turn fire her and replace her with her old friend and assistant. The town judge considers the whole mess a gross miscarriage of justice and demands a trial. This gives an ambitious young lawyer, the boyfriend of the new librarian the opportunity to do a little grandstanding by publicly proclaiming the highly-principled widow a communist. The poor woman suddenly finds herself the town pariah; her only remaining friend is a small boy she used to talk to in the library. He plays a key role in restoring her good name.
