seaQuest DSV

Captain Nathan Bridger is hauled out of retirement to command the new submarine SeaQuest, under the authority of the United Earth/Oceans Organization. His ship goes up against pirate forces commanded by Marilyn Stark, a former SeaQuest captain who tried to instigate a war.

While investigating a black smoker, Darwin becomes seriously ill. Bridger must contemplate setting his long-time aquatic pal free in order to save his life.

The seaQuest discovers the lost Library of Alexandria sunken beneath the sea. However, when surrounding nations cannot agree on a peaceful way to share the discovery, Bridger must act as mediator before escalating tensions result in the destruction of the library.

Mass murderer Dr. Rubin Zellar is unwittingly taken aboard the seaQuest. Placing him in custody, Zellar is able to escape and informs Bridger that he's hidden a toxin frozen in ice somewhere aboard the ship... a toxin that is surely melting with each passing second.
