Lindsey and Trevor are the perfect couple, who have just had the perfect wedding in Hawaii and are about to go on the perfect honeymoon on a cruise ship. It starts out like every other fairytale honeymoon. But when crew members discover Trevor and Lindsey are missing, the ship is put on high alert! Finally, after an exhaustive search of the vessel, Lindsey is found in a vacant stairwell, bloody and confused, with no recollection of what happened the night before.
With no sign of Trevor aboard the ship, he is presumed lost at sea and immediately a full-on investigation is launched by the ship’s Chief Security officer and spearheaded by vacationing FBI agent, Gwen Merced.
