Starr Carter (Amandla Stenberg) loves her family and her neighborhood, Garden Heights. She goes to predominantly white high school, but is fine with being the non-“ghetto” “Starr, version 2”  there and manages to shrug off the racist micro-aggressions from her classmates. Starr’s living a happy life, for the most part, until she witnesses the murder of a friend by a police officer.

In the new trailer for the “The Hate U Give,”  based on Angie Thomas’ best-selling YA novel of the same name, Starr begins to question everything after her friend is killed: race, privilege, justice. She’s told that the world is complex, that many factors led to the murder. “It doesn’t seem that complicated to me,” she declares.

Eventually Starr’s journey leads her to social justice activism, specifically the movement to end racially motivated police killings. (The novel and film are inspired by Black Lives Matter, but that name isn’t explicitly mentioned in the clip.) “It’s about more than just color,” Starr says. “It’s about black people, poor people, everybody at the bottom.”

“The Hate U Give” opens October 19. Directed by George Tillman Jr. (“Notorious”) and penned by Audrey Wells (“Under the Tuscan Sun”), the pic also stars Regina Hall (“Girls Trip”), Issa Rae (“Insecure”), Anthony Mackie (“Detroit”), Russell Hornsby (“Fences”), and Common (“The Tale”).
