After an affair with a client's husband leads to scandal, private chef Devon Paige is left with only one client in Boston—a reclusive professional basketball player with a craving for cookies. With no other choice, Devon lands on the doorstep of Rockwood, a boarding school on the New Hampshire seacoast, taking a job leading their dining services. She is shocked to soon discover Kyle Holling on staff, who she hasn't seen in over fifteen years since a memorable night just before departing for college in different cities. Devon and Kyle must determine what their relationship looks like years later, all while dodging the cameras of an underground newspaper, dealing with the installation of a controversial campus sculpture, and grappling with the arrival of Devon's former lover's daughter as a newly-enrolled student.

When Devon meets a handsome paramedic named Heath, she ditches the possibility of romance with Kyle in favor of what appears to be a more straightforward relationship. But a trip to Los Angeles to keep her client well-fed ahead of his basketball game threatens to upend everything, forcing Devon to finally answer the one question she has been avoiding: is fifteen years too late to rekindle a one-night stand?
