Hollis Shaw's life seems picture-perfect. She's the star of the popular food blog, Hungry with Hollis, and is married to Matthew, a dreamy heart surgeon. But after she and Matthew get into a heated argument one snowy morning, Matthew leaves for the airport and is killed in a car accident. The cracks in Hollis's perfect life-her strained marriage and her complicated relationship with her daughter, Caroline-grow deeper. When Hollis hears about something called the "Five-Star Weekend"-a woman invites her best friend from her teenage years, her twenties, her thirties, and mid-life-Hollis decides to host her own "Five-Star Weekend" on Nantucket. But her weekend won't be the Hallmark movie one might expect.
