Will Gardner, a disturbed Iraq War veteran, is suffering from a traumatic brain injury 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. During his journey, he tries to pick up the fallen pieces of the life he's lost since returning from combat. His PTSD causes frequent war flashbacks which he survives by having frequent conversations with Sam, his best friend and war buddy.
