The Storyteller (1970)

Chase, an Iraq war veteran suffering from PTSD delights in working nights as a janitor at a car museum, thoughtfully dusting, vacuuming, and polishing with striking attention to detail. His solo reverie is broken when an innocent little boy, who thinks he's called The Storyteller's Hotline, asks Chase to tell him a story that launches them into the world of 1960s car racing.
