Two documentary filmmakers appeared on "America's Newsroom" to discuss an ongoing project about American veterans suffering from PTSD following tours in Iraq and Afghanistan.

When the War Comes Home takes an intimate look at the lives of four service members and documents their successes and failures with various treatments for PTSD and TBI.

"It was such a privilege and honor to meet these folks and [have them] open their lives to us in their darkest hours," Executive Producer Jennifer Harris said.

"They suffer in ways we can't imagine. Just going to the grocery store is practically terrifying for some of them."

The film explores alternative methods that the filmmakers said have proven very effective, such as therapies incorporating animals, art, music and acupuncture.

One scene shows a veteran named Spencer out with his service dog that EP Debra Coleman Hyde said "has helped him tremendously." 

"He's able to go out now because the dog bridges that fearfulness he feels in society."

The filmmakers said many veterans, either because of their conditioning or not wanting to appear weak, are reluctant to ask for help even if they need it.

Harris said a focus is of the film is to let those people know, "Hey, you're not alone. We're here, we've got your back."
