It’s the story Behind the Movement.

Isaiah Washington, Loretta Devine and Meta Golding star in the forthcoming Rosa Parks biopic debuting on TV One next month. 

ET has an exclusive look at a new teaser for the film, which offers an inside look at the “three intense days” that led up to the 1955 Montgomery Bus Boycott.

Golding stars as Parks, with Marshall actor Roger Guenveur Smith playing her husband, Raymond Parks. Washington tackles the role of civil rights leader and organizer, E.D. Nixon, while Devine plays activist Jo Ann Robinson, and Shaun Clay portrays Dr. Martin Luther King Jr.

In the clip, Clay recreates a chilling rendition of King honoring Parks after she was famously arrested for refusing to give up her bus seat to a white passenger. 

Parks' bravery fueled a group of “everyday people” to stand up to racial injustice by launching what would become the “most successful boycott of its time.”

Although King, then only 26, was the prominent leader of the Montgomery, Alabama, boycott, he worked alongside a chorus of “lesser-known heroes” including Parks,who helped galvanize the over a year-long act of resistance. The boycott ended in 1965, when the Supreme Court ruled that bus segregation laws in both the city of Montgomery and the state of Alabama were unconstitutional.

Written by Katrina M. O’Gilvie and directed by Aric Avelino, Behind the Movement celebrates the contributions of the “unsung heroes” of a “watershed moment in the Civil Rights struggle.” 

Behind the Movement airs on February 11 at 7 p.m. ET/PT on TV One.

Watch the Oprah Winfrey and the cast of Selma pay homage to Dr. King, and the freedom fighters who changed history, in the video below.
