Three sisters. An inherited Nantucket restaurant. One year before they can sell.

Mandy, Emma, and Jill are as close as three sisters who live hundreds of miles apart can be. They grew up together on Nantucket, but Mandy is the only one that stayed.

Jill lives a glamorous life in Manhattan as a co-owner of a successful executive search firm. Never married, she is in her mid-30s and lives in a stunning, corner condo with breathtaking views of the city and Hudson river. Everyone thinks there's something going on with her partner, Billy, because as a workaholic, she spends more time with him than anyone else. There never has been, but Jill is starting to wonder if there could be.

Emma lives in Arizona and is an elementary school teacher and an aspiring photographer. She met her college professor husband, Peter, in grad school and they've been married for over 15 years. In recent years, she's noticed that Peter has grown distant. But when he shares a surprising secret, she doesn't see it coming and her world is turned upside down.

Mandy has two children and is married to her college sweetheart, Cory, who runs a wildly successful hedge fund from Nantucket. Now that the children are older, Mandy has more free time and is eager to do more than just volunteer with local charity events. But Cory doesn't want her to work. He thinks it doesn't reflect well on him and appearances are everything to Cory. Though when Mandy finds something unusual in his gym bag, she begins to question what is really going on.

The girls are stunned when they learn about the restaurant, Mimi's Place, and the condition their grandmother added to the will, leaving the restaurant equally to Mandy, Emma, and Jill - and also to Paul, the chef for the past 12 years, and Emma's first love.
