“Do your recon,” Brian Cox says to Sinqua Walls in the 2022 film Mending the Line. “More great literature has been written about fly-fishing than any other sport.” So begins a reluctant friendship between two military men that grows while they wade in Montana’s shallow waters waiting for pike to bite. 

From director Joshua Caldwell (Infamous), the film centers around a Marine living with trauma (Walls) who learns to face his struggles head-on as he fosters an unlikely friendship with an older veteran (Cox).

What happens in Mending the Line?

Colter (Walls), a sergeant in the Marines, has just returned from Afghanistan, where he was wounded right before his tour ended. He’s tormented by flashbacks and nightmares about what happened to his fellow Marines and racked with guilt that he was unable to prevent casualties among them. Now, after passing through a few rehab facilities, he’s desperate to return to active duty but he’s just not ready yet — his post-traumatic stress disorder symptoms are nearly unmanageable. So when Colter meets Dr. Burke (Heaton) at the VA center, she pairs him up with an older veteran and fly-fisher named Ike (Cox), whose health is in decline. Ike is on strict orders from Dr. Burke to not fly-fish alone, and he’s initially resentful of Colter’s company — but as the two begin to spend their days together, they realize they have far more in common than either expected. And when Colter meets librarian and VA center volunteer Lucy (Mattfeld), his outlook on life gets a little bit brighter.
