Fin McBride can work up far more passion for trains than people. When Fin’s train-store boss dies and leaves him an abandoned depot, Fin hopes solitude will at last be his. He arrives in town a man who does not want to be bothered. But his life unwittingly intersects with the tracks of two others: a grieving painter (Clarkson) who nearly runs Fin over and a lonely, motor-mouthed hot dog vendor (Bobby Cannavale) always hungry for conversation. In spite of himself, and entirely by surprise, Fin becomes swept up in their lives, and even in a romance with the town’s sexually provocative librarian (Michelle Williams) — as he reinvents himself as the catalytic center of a community.
