The true story of Richard and Mildred Loving (Joel Edgerton, Ruth Negga), an interracial couple who defied Virginia's anti-miscegenation laws by marrying in 1958, when Mildred found she was pregnant at age 18. After their house was raided by local police in the middle of the night, the Lovings were threatened with prison, and instead opted to be exiled to Washington D.C. for violating the law by getting married.
However, after years of living in the city, they grew tired of not being able to live near their families in the country where they'd been raised and had lived for so many years. When one of their children was struck by a car on a city street, they finally moved back home, even though they were facing being arrested again. They obtained legal help to sue the state of Virginia in an attempt to strike down the rules, and allow interracial marriages to be seen as legitimate in the eyes of the law.
