A picture perfect, beachfront wedding in Hawaii is shattered when a deranged, gun-wielding man bursts into the chapel, taking the bride and her young son hostage. The maid-of-honor, Claire Hedgleigh, Forensic Instincts' resident psychic, stays behind to help her best friend. In a twist of fate, FBI agents Sloane Burbank and Derek Parker are honeymooning at the same hotel, and take charge of the hostage negotiations while law enforcement is en route.
Sloane, Derek, and Claire are in a race against time as a brittle personality with nothing to lose stands in the way of happily-ever-after for all.
