Macklin Celebrini is a former hockey prodigy turned Boston University student who gave up the sport under pressure before unexpectedly getting pulled back into its orbit. Now working late nights driving a campus safety cart, he spends his quiet shifts trying to stay invisible—until repeated 3 a.m. calls from Boston College hockey star Will Smith start pulling him into a world he thought he left behind. What begins as routine pickups slowly turns into something that challenges everything Mack thought he wanted, especially as Will becomes impossible to ignore.
