A weary conductor on the late-night route notices how passengers in the packed cars sometimes find unexpected closeness amid the jostling crowd. Rather than look away, he recognizes an opportunity in these fleeting, wordless encounters and decides to put the empty train to new use once the final stop is reached. With the lights low and the cars at rest, he quietly arranges private meetings for those seeking the same discreet comfort. The first episode shows the ordinary midnight line becoming something altogether more inviting.
