It's never too late to get back on track.
Michael is a broken man. He's waiting for the 9.46 to Gloucester, so as to reach Crewe for 11.22: the platforms are long at Crewe, and he can walk easily into the path of a high-speed train to London. He's planned it all: a net of tangerines (for when the refreshments trolley is cancelled), and a juice carton filled with neat whisky (for Dutch courage). He has his last credit card taped to the inside of his shoe - and that should make identification swift and easy.
What Michael hasn't factored in is the twelve minute delay, which risks him missing his connection, and making new ones. He longs to silence the voices in his own head: ex-girlfriends, work colleagues, and the memories from his schooldays, decades old. They all torment him. What he really needs is someone to listen, and help him make sense of his grief.
Journeys intersect. People find people when and where they least expect it. A missed connection needn't be a disaster: it can save your life.
