SGT. Will Gardner tells the story of Iraq War veteran Will Gardner (Max Martini) who is suffering from a traumatic brain injury (TBI) he sustained with his platoon while in combat. His injuries make it difficult for him to reintegrate into society. After a series of setbacks, he embarks on a spirited motorcycle journey across America with the goal of reuniting with his son. Along his journey, he tries to pick up the pieces of the life he's lost since returning from combat. His PTSD causes frequent flashbacks to the Iraq War which he survives by having frequent conversations with Sam (Omari Hardwick),his best friend and war buddy. Martini (13 Hours, Captain Phillips) also penned the script and directs the film.
