The beginning of a relationship is usually all about getting to know each other, sharing stories far into the night, comparing experiences, triumphs and heartaches, until we know one another inside out. Not so for Dave and Alena. He's from London, she's from Siberia. They meet in a sleek Bond Street department store in the frayed heat of high summer, where she's up to no good and it's his job to catch her. So begins an unlikely relationship between two people with pasts, with secrets, they've no idea how to live with - or leave behind. But despite everything they don't have in common, all the details they won't and can't reveal, they still find themselves fighting with all they've got for a future together. An unconventional, will-they-won't-they love story, that takes us from London to Siberia, and from hope to heartbreak, and back again.
