Vacationland follows top LAPD detective Grace Chen after she resigns from her job in disgust. She retires to the quirky village of Serenity, Maine, determined to put it all behind her. When Serenity's Sheriff is murdered, however, Grace finds herself dragged back into crime fighting by Joey, a local veterinarian and amateur sleuth determined to protect the town she loves.

Between Grace's big-city detective skills and Joey's understanding of Maine, they turn out to be a surprisingly effective team … and a very unlikely pair of friends.
