EMT Elly Finnegan instinctively jumps into the line of danger when a gunman opens fire at the Christmas parade. Despite hating the sight of blood, she acts exactly as she's trained to do. Tactical officer Joe Kingsley is there, too and they work together to save lives. But when more shots are taken near her home, Elly and Joe realize the danger is far from over. Joe promises Elly's brother Rhy that he'll protect the youngest Finnegan sibling with his life. But as danger stalks them, it proves a difficult promise to keep. This shooter wasn't your typical rage filled young man-this guy had a cold and deadly purpose. And it was up to Joe and the rest of the tactical team to uncover his motive before he strikes again. Can Joe keep Elly safe so she can celebrate her Christmas family reunion with the Callahans?
