One summer a group of strangers - each with their own reasons for wanting to step out of their busy lives - meet at a rented beach house in sunny Nantucket, owned by the mischievous and free-spirited Nan. There's Daniel, who's causing heartbreak for his wife Bee; recently divorced Daff, who feels she's lost touch with her daughter Jess; and Michael - Nan's son - who is having an ill-advised fling with his boss.
With so many lost souls gathered under one roof, very soon there are tears and laughter, friendship and - for some - even love. Each one of them is hoping for a new beginning. But will any of them find it?
