Virgil ‘Bud’ Brigman (Ed Harris) is the lead foreman of Deepcore, an underwater oil drilling rig 2,000-feet deep. Deepcore receives word of a downed US Navy nuclear submarine in the area near the Cayman Trough. As Russian subs are close by, foul play is suspected. The crew must escort Bud’s soon-to-be ex-wife Lindsay (Mary Elizabeth Mastrantonio), the project engineer for Deepcore, and a crew of Navy SEALs for a rescue mission. A hurricane cuts communication outside, effectively leaving Navy SEAL Lieutenant Coffey (Michael Biehn) in command. Psychosis from pressurization makes Coffey unstable and paranoid, viewing the various neon-colored NTIs (Non-Terrestrial Intelligence) in a nearby abyss as enemy Russian vessels that must be destroyed. James Cameron writes and directs.

Scientists on the last few days of their stint in a deep sea mining operation stumble upon a mysterious Russian ship, “Leviathan”, which has sunk and perhaps was ambushed by their own navy. They loot some cargo on board and inadvertently bring back the remnants of a genetic experiment gone awry, which they also set loose upon their own vessel, to gruesome and nightmarish results. Peter Weller, Amanda Pays, Richard Crenna, Daniel Stern, Ernie Hudson, and Hector Elizondo appear in this film directed by George Cosmatos.
