The story takes place on a cruise ship that is heading for Boston. Halfway through, the cruise ship was hit by a violent storm and eventually broke anchor. Cracks appeared in the ship, and a large amount of seawater began to seep into the hull. If it is not controlled, the entire cruise ship will be at risk of sinking. Ray (Casey Affleck) is the highest-ranking crew member on the ship, which means that he has an unshirkable responsibility for the lives of the 30 crew members on board. The experienced Ray decided not to sit still and wait for death, but led the crew to launch a self-rescue operation. At the same time, the Massachusetts Coast Guard received a distress signal from the cruise ship and sent a rescue team for search and rescue. Bernie (Chris Pine) is the captain of the search and rescue team. Under his leadership, four team members drove a very simple wooden lifeboat into the vast ocean.
