An uplifting and heartwarming story about finding the magic of Christmas, no matter where you might be, This Is Christmas follows Adam (Alfred Enoch) and Emma (Kaya Scodelario) as they make their daily commute from the picture-perfect village of Langton to London for work. Every day they share their journey with the same characters, but they all keep themselves to themselves. But then one day, in the build-up to Christmas, Adam breaks the unwritten rule of travel and starts talking to the strangers on the train, inviting the whole carriage to hold their own Christmas party.
