On a dark, foggy night, the William S. Mitchell steamboat careened into a bridge, killing many on board, including the captain and his daughter. Ever since, anyone who has worked on the now-defunct ship has been doomed to die onboard — at least 112 have — cursed to forever haunt the vessel along with the other deceased. Workers have sworn they’ve heard the captain’s daughter’s screams and seen her body roaming the ship, fearful that she is the cause of the mysterious deaths. The only way to find out is to see for yourself — and luckily the USS Nightmare just had its opening weekend. Let the haunting begin.
