When Roz's silent, compulsive husband refused to discuss his problem, when her children seemed embroiled in their own lives, Roz did the unthinkable - she walked out. She did not know that her children would not understand, would not forgive her. She had one moment of joy, shutting the door, leaving, followed by ten years of guilt.

Then the death of the family matriarch Nan reunites Roz, now with a career, a flat and a lover, with her family. Histrionic Zoe and infuriatingly laid-back Jamie arrive on her doorstep. Suddenly Roz is a mother again. A human soup is stirred, and dark family secrets are revealed. But Roz soon realises that her children have only returned to her so that, in the proper scheme of things, they can leave her. Rather than she leaving them.
