Heather Shaner, a feisty, blue-haired public defender in Washington, DC, has spent over 40 years representing people who can't afford a lawyer. But her empathy hits a limit when a violent mob supporting outgoing President Donald Trump storms the U.S. Capitol. She is assigned to represent Jack Griffith, a social media influencer, and Annie Howell, a single mother and painter. As Heather gets to know her clients, she discovers Jack and Annie were deceived by misinformation and thought they'd joined a righteous defense of democracy, not an authoritarian wave. PUBLIC DEFENDER explores the delicate state of U.S. democracy, the forces threatening to tear it apart, and the people dedicated to protecting it. Amidst a growing political divide, when trust is lost, the unlikely bonds between Heather and her clients reveal how people can rise above the fray to find each other's humanity.
