We see a train passing by to our right and quickly realize we are on a train as well, or at least the cameraman here is. The previous train just came out of a tunnel and ours is about to get in. As we enter, darkness is everywhere. Quickly the action switches to inside the tunnel and we see man and a woman sitting on opposing seats. The man wearing a cylinder gives a couple innocent kisses to the lady, probably his wife, yet displays of affection in public weren't really too common back in the day while you see people making out everywhere 115 years later. As the end of the tunnel is reached, the two sit back again and behave "normal" by reading books. Okay short film, but I don't think it's really that relevant in cinema history as some people make it out to be and it's certainly way less explicit then the Bamforth remake from the same year.
