Unimaginable adventure awaits in the spectacular undersea world of SeaQuest DSV. The amazing journey begins in the mid-21st century, as humankind expands its undersea colonisation efforts and a tenuous world peace is enforced by the United Earth Oceans (UEO). In order to protect the fledgling underwater colonies from unknown dangers and hostile invaders lurking in the depths of Earths last frontier, the UEO recruits Captain Nathan Bridger (Roy Scheider) to command the high-tech battle submarine SeaQuest and its diverse crew.
