There Goes the Bride

S1, E15: Jack and his squad investigate a bride, Audrey Rose (Kelly Overton), who disappears from her wedding celebration. The groom, Charlie Beckworth (MacKenzie Astin), has no explanation, although it appears that she left with someone she knew. The team learns that Audrey had a troubled past and was being blackmailed by a man who videotaped her cheating on her unsuspecting fiancée. When the investigators find the blackmailer dead at an abandoned building with no trace of Audrey, they begin to suspect that a member of Charlie's family may be involved in the disappearance.
