Thanksgiving is here, and while Maddie Graves is thrilled to be sharing the holiday with the love of her life, Nick Winters, she's also slightly manic about hosting her first big family meal, but that's cause for family hijinks more than actual worry.Maddie's anxiety shifts to a new problem when Detroit Detective Dwight Kincaid - a man Maddie worked with for years as he searched for missing people - shows up on her doorstep. It seems Dwight's daughter Sage, a freshman at a local college, has gone missing. Dwight needs Maddie's help to find her.Nick volunteers his time to help, but he's terrified Maddie will fall into despair if the search for Sage doesn't go as planned and Dwight doesn't get the happy outcome Maddie desperately wants for him. When the trio hits the campus, things turn dark and deadly quickly.Between an out-of-control fraternity, two friends who seem more like enemies than allies, and a secret about Sage herself that throws Maddie for a loop, the group has a lot on their plates. For his part, Dwight seems resigned to his daughter's death while Maddie refuses to give up hope and won't listen to reason when Nick tries to talk her down from a perilous ledge.As the pieces start falling into place, Maddie realizes something even more nefarious is going on. Will it be too late to save Sage, though? And when a killer sets his sights on Maddie, will she escape and make it to another family holiday?
