Though everyone knows the story of Rosa Parks’ refusal to rise from her seat on a bus at some point and the impact it had on the Civil Rights Movement, few know the story of the girl behind the motion.

Peacock’s latest documentary, The Rebellious Lifetime of Mrs. Rosa Parks, finally pulls back the curtain on the girl whose easy “no” became the spark that led to the blaze of desegregation within the Jim Crow South in the course of the 1950’s.

The film tells the unexpected story of Parks and her life beyond the historic bus boycott in Montgomery, Alabama, turning Parks’ story on its head and revealing the intent behind her activism, her radical politics and the true extent of her courage. 

Told via a wealth of video footage, exclusive audio of Parks herself, and a wide selection of interview subjects, including activists, celebrities, and Parks’ own members of the family, the film paints an honest and evocative picture of her defiant spirit, the countless hardships she faced over the course of her life, and examined how her legacy continues on in today’s ongoing long path toward justice and equality.   

“I felt that I had a message, but people didn’t decide to take heed to what I used to be saying,” Parks might be seen saying in her own words in the course of the trailer.

The film breaks down not only that fateful day on that Montgomery bus, but her a long time of radical activism, and even her little-known dealings with the Black Panther Party.

Take a have a look at the trailer below.

Executive produced by Soledad O’Brien, Jo Honig, Patrick Conway, and Co-executive produced and directed by Yoruba Richen and Johanna Hamilton, The Rebellious Lifetime of Mrs. Rosa Parks premieres only on Peacock on October 19.
