The "Gigantic Overseas Autoliner" is a documentary about the Trapper, the world's largest automobile transporter. The loading process is a daunting task with around 10,000 cars and other heavy cargoes that need to move through the same door with limited space and time. Despite the challenges, the crew manages to park 1,000 cars ahead of schedule, and hundreds of tons of high and heavy cargo make their way onto the deck before departure. The crew navigates the Trapper through the Panama Canal, maneuvering carefully through the narrow confines of the canal. The journey takes nine hours and saves the ship three weeks of travel time, and after over 28,000 kilometers, the Trapper safely arrives at its first port in Auckland, New Zealand. Thanks to the meticulous planning of the unflappable port captain and the dedication of the dock workers, thousands of new cars and hundreds of the heaviest vehicles find their way to new owners, making this mega transport possible.
