Spread across the country but connected through private Facebook groups, more than 30,000 conservative, Christian mothers call themselves “mama bears” because of how ferociously they fight for the civil rights of their children and the entire LGBTQ+ community. The film explores the journeys of two mama bears and a young lesbian whose struggle for self-acceptance exemplifies why the mama-bears movement is vitally important. Shot in a poetic, deeply intimate style, “Mama Bears” uses social-media posts, home movies, photographs, interviews, and cinéma vérité footage to explore the complex intersections of politics, religion, faith, and true, unconditional love.
