Samantha and her family are taking a cruise on the Titanic 2, a replica of the original Titanic. From the first day, Samantha and her sister, Jessica, notice strange things happening. Their cabin number keeps changing. There are creepy scratching sounds coming from between the walls. And a locket that Jess opened at the museum seems to be...following them. Is the locket haunted? Or could it be the ship itself? Are there actors in costume walking about the ship...or could they be ghosts? Why is Sam's sister calling her by another name? Samantha will have to unravel the threads tying her and her sister to the past, or they could go down with the ship!
