 Charles Lattimer is an everyday man facing middle age and a marriage coming to an end, who stumbles across a time slip, that occurs on one of his regular train journeys (as the train goes through a tunnel) coming across an antique watch, he learns it allows him to get off the train during the time-slip, whereupon he finds himself back in the 1890s. Before long he finds a new found love, and purpose there. But complications occur when first the portal back too the past starts to close with his timepiece breaking soon after, leading to decision that could leave him stranded out of his own time.
