After his ambulance is T-boned and sent careening down an embankment, medic Jay Barlow faces a life without the use of his legs and a depression that cannot be consoled by his loving wife of 26 years and supportive adult children. But when an opportunity to become a docent at the Smithsonian National Air and Space Museum is presented to him, Jay begins to see a way out of his despair as he gives tours from his wheelchair and immerses himself in the impressive collection of artifacts and the stories of the military veterans who volunteer there. He eventually finds himself in a world where he can escape his physical limitations and become a part of history. Jay's experiences become increasingly fantastic to the point where his wife Debbie, a registered nurse, becomes concerned that they are a product of PTSD.
