Arizona native Dierks Bentley is proud to have one of his songs appear in an upcoming film based on true, but tragic, events that took place in his home state in 2013.

The movie, titled Only the Brave, is about the heroism of the Granite Mountain Hotshots. The firefighters took on the deadliest fire ever in Arizona, and the worst in the U.S. since 1933. 19 of the 20 members of the crew were killed in the devastating event.

Bentley has a personal connection to the events, not only being from Arizona but also having held a fundraising concert after the tragedy to support the families of the firemen who died. The Country Cares concert took place in 2013 and also featured Randy Houser, the Band Perry and David Nail. It raised $476,000 and was presented alongside Brandon McDonough, the only surviving member of the crew.

“So honored to have a song in this film. It sheds light on the lifestyle of wilderness fire fighters and honors these men and their families,” Bentley wrote on Twitter after posting the trailer. Bentley hasn't revealed the title of the song in the movie.

Only the Brave is slated for release in theaters Oct. 20, 2017.

According to the Fire & Aviation Management website, "Hotshots meet stringent qualifications and work in some of the roughest and most remote terrain in the nation. They are highly mobile and trained to be self-sufficient with their own vehicles, gear, and specialized firefighting tools."

Bentley just released a new music video for his song "What the Hell Did I Say," the song for which he named his What the Hell Tour, which he recently extended. He’s currently on the road with Cole Swindell and Jon Pardi as openers.

"It seemed like an appropriate title for a tour with Cole and Pardi," Bentley says. "I have a feeling I’ll be asking myself that question the morning after many of our shows and late night hangs because you really don’t know what will happen when the three of us get together."
