Jaime, new to London with her boyfriend, longs to find a fun crowd. And Bryony is trying to remember the promising young woman she was, before a positive pregnancy test set her life on a different course.

After a few evenings, the strangers begin to see they have more in common than they realised. But when everyone's secrets are finally out on the table, will it sabotage the team's chances?
