When we talk about PTSD, we always talk about the servicemen and women who have this hidden injury. It is a silent killer and is attributed to the high rates of suicide among U.S. military veterans. According to a study released by the Department of Veterans Affairs released in 2013, there were 22 deaths a day, or one every 65 minutes. Apart from that, a number find themselves unemployed, depressed, and homeless.

But it's not only them that get PTSD, even the K9s that accompanied soldiers on missions also experience PTSD that can be caused by the harrowing experiences in some of the missions, such as the unfortunate loss of their handlers they accompany.

Max, a movie set to be released by Warner Bros. in June 26, is all about that and some say it promises to be tearjerker.

Max is a USMC K9 that served in Afghanistan with his handler, U.S. Marine Kyle Wincott. But on a maneuvers things went horribly wrong.

Max was traumatized by what happened to his handler who was mortally wounded. Unable to do what he has been trained to do, he was sent back to the States. Once there, he was difficult to handle, and only seems to welcome the presence of Wincott's younger brother,  Justin. With Max being part of Wincott's life, the family adopted Max.

With the help of a friend, Justin was able to establish a bond with Max.  As the trailer continues, there is an indication that what happened to his brother was no accident, and that friends in his unit had something to do with it.  Justin and Max now have a mission of finding out what really happened in Afghanistan that led to his brother's death.

Directed and co-written by Boaz Yakin (Remember The Titans), "Max" stars Josh Wiggins as Justin Wincott, Lauren as his mom, Pamela, and Thomas Haden Church as Ray, his dad. Robbie Amell of "The Flash" TV series is Kyle Wincott.
