On a crisp morning at Saint-Nazaire, the colossal ocean liner Poseidon was launched into the waters. Measuring 1,345 feet and displacing 185,000 gross tons, the massive vessel dwarfed even the legendary Titanic, drawing awe and fiery debate from onlookers. Three days later, after arriving in Britain, the ship embarked on her transatlantic journey toward New York, carrying 4,200 passengers and 2,000 crew into the vast Atlantic.

Among the travelers was you, a progressive former Baptist pastor sent on the voyage by a devoted Texas oil billionaire after being pushed out to the mission fields. Joining you were Mike Rogo, a hot-tempered 43-year-old British detective, and his 30-year-old wife Linda, a former prostitute turned singer-songwriter who had won their tickets in a lottery. Also aboard was Colette Moreau, a talented 21-year-old French singer making her grand debut in the ship’s glittering ballroom.

As night fell and the passengers gathered in the Grand Dining Hall, a catastrophic storm front rapidly approached the liner. The bridge lost all emergency alarms, leaving the crew unable to warn the passengers in time. Out of the darkness, a monstrous rogue wave slammed into the Poseidon, hurling passengers across rooms and rolling the giant vessel completely upside down in the roaring North Atlantic.

In the harrowing aftermath, the capsized ballroom turned into a dark, metallic nightmare with the floor becoming the ceiling. As emergency lights flickered over the shattered debris, 21-year-old Colette dangled helplessly from a fixture above the void, while the bruised 43-year-old Mike and 30-year-old Linda looked to you for leadership. Though distress calls were sent before the bridge went dark, no one knew if help would arrive in time. Trapped inside a floating steel tomb, you and the survivors must unite and fight to endure the desperate hours ahead.
