A heart-warming tale of Tom (Timothy Spall), a pensioner whose wife, Mary (Phyllis Logan), has just died, who travels from mainland Britain's most northerly point, John O'Groats, to his original home town at England's most westerly point, Land's End (NOT its most southerly, as this is Lizard Point, some miles away), using his free bus pass. He carries with him only a small suitcase, travelling the length of the country with it. Along the way, his adventures are recorded by the people he meets and helps, and by the end of his trip he has unwittingly become a social media celebrity.
