1964, The Georgia Lance is going for its daily tour down the Savannah River. The tour is supposed to be an hour, but this trip feels longer. Two hours past, then three. The passengers get both confused and furious, and they head up to the cockpit, only to find him lying drugged and passed out on the floor. They can't wake him for the life of them, and no one else on board knows how to man the wheel. Late that night, he wakes up, everyone on board still miserable. The captain tells everyone that they have drifted out into the Atlantic Ocean, and that he was drugged. At the same time, an esteemed Georgia businessman is found dead behind the bar. Now, the ship is stuck in the Atlantic Ocean, communications cut off, a dead man on deck, and a vicious murderer prowling around.
