Suzie is struggling through one of the hardest days of her life - the funeral of her husband Frank. David arrives, unexpectedly, to support her through it. But there's only so much support you can accept from the man you're steadily falling in love with, when you're supposed to be busy burying your husband.

It's over two years since Suzie and David sat next to each other on a train journey from London to Penzance. Both married, they shared an intense and unforgettable five and a half hours. Since then they've both enjoyed escaping their middle-aged lives together. But now there's no escape from reality; it's crunch time for their relationship.
