Sarah and Liam have been competing against each other since they were schoolchildren, striving to best the other in everything from student body elections to college applications. That rivalry continues to drive their interactions as mayors of East and West Riverton, New Hampshire, quaint towns that are perennial contestants in the annual “New Hampshire Christmas Spirit” contest. Determined to lead their beloved hamlets to victory, Sarah and Liam nearly let their competitive instincts get the better of them before calling a truce. When both towns are chosen as finalists, the mayors have just five days to plan a celebration that shows what Christmas means to their community. Their surprising collaboration yields not only a magical event but also a Christmas miracle: love.
