Returning to the past, he found his future.

Widower Tom, on the recent passing of his wife Mary, uses his free bus pass to travel the length of Britain from John O'Groats in Caithness to Land's End in Cornwall, their shared birthplace, using only local buses. It's an incident-fuelled nostalgia trip and his encounters with local people make him a media phenomenon. Tom is totally unaware and to his surprise on arrival at Land’s End he’s greeted as a celebrity.
