Brandi's wedding day has finally arrived, and Mary finds herself torn between two duties: job and family. The one day of the year she can't be at work, Maid of Honor Mary is called in to testify about her role in the sting on arms dealer Julian Conran, and she can only hope to get to the courthouse and the church (or in this case, the country club) on time.
Complicating matters is the fact that Mary is confronted with two rather unwelcome visitors: her ex-husband (and baby daddy) Mark, and Ronnie Dalembert/McIntyre – the con man Mary met and detested only a few months earlier. While Mark comes through for Mary, Ronnie manages to screw things up for everyone yet again. Only this time, things get really ugly for the WitSec team when, while escorting Ronnie to give his testimony, Mary, Marshall, Stan and Delia find themselves trapped in the courthouse and ambushed by assassins.
As they fend off their attackers, Brandi battles her own wedding-induced panic. With cold feet getting the better of her and Mary and her unborn child facing serious danger, Brandi's big day is certainly full of drama.
