I Was There (2016)

"When you hit bottom the only way is up."

Gus Johnson (James A. Lee) is a New York City firefighter who barely escaped the World Trade Center on 9/11 and instantly became a hero. Except the only reason he survived was because he panicked and ran away, a secret he kept hidden under PTSD and survivor's guilt. Years later, Samuel Lyons (Carl Ford), a photographer who crossed paths with Gus on 9/11, confronts Gus with a photo that proves Gus was a coward. Samuel blackmails Gus into telling the truth to his family, forcing him into a journey of self-discovery and acceptance which reunites him with his son Frankie (Sebastián Zurita) who enlisted in the military to fight for him.
