Supervisory Special Agent Finn Callaghan is impressed. While teaching a course at Quantico, he witnessed trainee agent Kennedy Morris take down a bully twice her size. Before leaving Washington DC, he stops by her apartment to offer her a job as his partner in Granite City, Montana and is surprised to see a wedding reception in her building during the worst storm of the year.

Kennedy is having a bad day. Her FBI training isn't going well, her dysfunctional family is visiting, there's a category one hurricane bearing down on them, and now she has to deal with her attraction to her superior Finn Callaghan.

When the bride from the reception, Vanessa Stevens, disappears, Finn offers to help. With Kennedy's aid, they delve into the world of the rich and powerful. But their investigation reveals that no one really knows Vanessa. When the storm cuts the power and phone lines, they must ascertain if kidnappers have taken advantage of the weather or if the bride is a clever con woman.
