Tonight on ABC, it’s the debut of Women of the Movement — a limited series that tells the true story of Mamie Till-Mobley and her fight for justice after her 14-year-old son, Emmett Till, was lynched and murdered by a white mob in Mississippi in 1955.

Adrienne Warren stars, and she hopes the series has a big impact on people.

“You get to hopefully look at this story and it humanizes these incidents for you,” she says. “That when you find out that someone’s son is taken from them, or their child is taken from them, that you realize that is not just a person, a picture on the screen, but that’s an empty seat at your kitchen table. That that’s an empty seat when you’re having holidays. That that is someone’s loved one.”

Warren, who plays Till-Mobley, says it’s an important story for people to know, and it’s not just history, it’s happening.

“We must know our history so that we don’t repeat it,” she explains. “And there are women, and mothers, screaming right now for justice for their sons, for their daughters, for their families, and we don’t talk about those families enough.”

Women of the Movement premieres tonight at 8 p.m. ET on ABC.
