Stationed deep below the ocean’s surface, a crew of scientists are suddenly cut off from the outside world by an unprecedented seismic event. The quake causes a mysterious specimen to be unleashed, transforming from a seemingly innocuous goo into a large, bizarre-looking alien creature. Technician Claire McDowell (Priscilla Barnes, Three's Company, Mallrats) attempts to study this unexpected phenomenon, with her commanding officer, Dobler (Bradford Dillman, Piranha), dead set against it. The tensions and intrigue build to a terrifying climax in this Roger Corman-produced undersea adventure featuring eye-popping visuals from the award-winning special effects team who brought you Aliens.
