On the last train home you expect to find standing space only, drunk people singing, the overpowering smell of McDonalds...
You never expect to find love.
When Abbie and Tom cross paths traveling home after a night out, their eyes meet across a crowded carriage and their connection is unmistakable.
What they don't know is that moments later they will both be caught up in an event that will change them forever.
It's one that will bring them together. But it will also tear them apart.
A lot can happen in seven seconds. A lot can happen in seven years.
Can they find their way back to each other?
