“If you knew in your heart and in your mind that someone took your child’s life, how far would you go to get to the truth?” asks Claudia Lacy in a new trailer for “Always in Season.”  Jacqueline Olive’s award-winning documentary sees Lacy seeking justice for her son, Lennon, who was found hanging from a swing set in Bladenboro, North Carolina.

Authorities ruled Lennon’s death a suicide despite suspicious details. His mother doesn’t buy their theory. She’s convinced he was lynched and is demanding answers.

“Always in Season” made its world premiere at Sundance in January, where it took home a Special Jury Award for Moral Urgency. The feature’s other honors include Best Documentary at Omaha Film Festival and the Grand Jury Prize for Documentary Feature at Dallas International Film Festival.

“While I was making this film about lynching, discovering increasingly more about the impact of decades-old racial terrorism that hundreds of communities are still facing, I was also raising my son, watching him grow from a boy who was typically considered adorable into a young man who could now be perceived as a threat,” Olive told us. “Our ongoing conversations about racial profiling and violence became increasingly specific to my son as we discussed ways he could protect himself. It became all the more urgent that I make a film that gives historical context to the racial violence going on today, while highlighting efforts for justice and reconciliation.”

“Always in Season” arrives in theaters September 20.
