The McKenzies are your average complicated family: knotted together by in-jokes, arguments and a few closely-guarded secrets. Thirty-something sisters Leni and Alice became inseparable following the divorce of their parents, Belinda and Tony, with younger brother Will always trying to keep up. They're not perfect, but they love each other - most of the time, anyway.

But then one ordinary summer day, an accident changes the family forever. Questions arise, guilt surfaces and secrets begin to emerge. Scattered by grief and seeking comfort in the unlikeliest of places, can the McKenzies find their way back to each other?
