A divorced mother, Harper, runs a small retail store in New York City, while working on her pet project, Six Degrees of Santa, which aims to spread human connection during the holiday season. Jason, her former tech industry boss, launches a mail-order Christmas tree service and becomes the recipient of a gift from the project, which leads him to Harper. He proposes she help him find the original giver, Santa #1, in exchange for expanding the online reach of her store. Harper agrees, but only if Zoe, a social media influencer, becomes Santa #1, as she sees a business opportunity. However, Zoe starts to develop feelings for Jason, and Harper struggles to reveal her true identity as Santa #1, fearing it will ruin her growing bond with Jason.
