How do you know if you’re with the love of your life?

David Tennant, Ashley Walters, Billie Piper, Jane Horrocks, and David Morrissey star in BBC1’s first ever improvised series, exploring five powerful and overlapping love stories set in the same town.

When it comes to love, there is never an easy "right answer" – telling the truth is complicated, and the conflict of desire and responsibility can be explosive.

These stories are life-affirming, visceral, provocative and compelling. Did the characters do the right thing in the end? What would you have done? The themes are universal, yet they provoke wildly different responses.
