A woman searches for answers after her son’s death in a newly released trailer for Katherine Dieckmann’s “Strange Weather.” Darcy’s (Holly Hunter) son killed himself seven years ago, but she can’t move on — especially because she suspects her late son’s friend, Mark, stole his business plan. She embarks on a road trip through the deep South to confront Mark, who now runs a lucrative chain of restaurants.

“I’m here for moral support,” says Darcy’s best friend Byrd (Carrie Coon, “The Leftovers”). She adds, “I am not accompanying you on some mission of violence.” Byrd’s fears aren’t unfounded — Darcy has brought along a gun.

Darcy is convinced that Mark is a villain and her son is a victim, but Byrd seems to think she’s oversimplifying the situation and jumping to conclusions. “It’s like the way you see the world is the only way to see it. That’s just the story you’ve been telling yourself — that doesn’t mean it’s how it actually was,” Byrd says.

“I wanted to explore the complicated path of an unconventional female protagonist in a way that felt real to me in terms of the women I actually know in my life — women I rarely if ever get to see represented on the big screen,” Dieckmann told us. “They have reached a certain age but remain unresolved, alive, contradictory, compelling, and not prone to stereotyping.”

She continued, “‘Strange Weather’ deals with female friendship, learning to see outside the sphere of your own personal pain, and finding ways to overcome that pain in the process. These are all ideas that I was interested in exploring in a feature, and this story allowed me the context to dive into all of them.”

Dieckmann’s credits include “Motherhood,” “Diggers,” and “A Good Baby.”

Hunter won an Oscar in 1994 for “The Piano.” She also earned nods for “Thirteen,” “The Firm,” and “Broadcast News.” You can catch her next in Sundance hit “The Big Sick,” co-written by Emily V. Gordon. The critically acclaimed romantic comedy hits theaters June 23.

“Strange Weather” hits theaters and VOD July 28.
