DeepStar Six

DeepStar Six (released in the Philippines as Alien from the Deep) is a 1989 American science-fiction horror film about the struggles of the crew of an underwater military outpost to defend their base against the attacks of a sea monster (possibly a giant eurypterid). It was released in January 1989. The film's main actors and supporting players included Greg Evigan, Taurean Blacque, Nancy Everhard, Cindy Pickett, Miguel Ferrer, Nia Peeples, and Matt McCoy. Plot DeepStar Six is an experimental deep-sea US Naval facility, crewed by a mix of 11 military and civilians, now in the final week of their tour. The project is headed by John Van Gelder, to test underwater colonization methods, while overseeing the installation of a new nuclear missile storage platform. Already nearing his deadline, Van Gelder's plans are threatened when geologist Burciaga discovers a massive cavern system under the site. Van Gelder orders the use of depth charges to collapse the cavern, to the dismay of Dr. Scarpelli, who wants to study the potentially primordial ecosystem inside. The ensuing detonation collapses part of the seabed, forming a massive fissure in the ocean floor. Submarine "Sea Crab" pilots Osborne and Hodges send an unmanned probe to explore, but lose contact and venture in after it. Upon finding the probe, they detect a large sonar contact moments before being attacked and killed by an unseen entity. The aggressor then attacks the observation pod "Sea Star", leaving Joyce Collins and a dying Burciaga trapped inside as it teeters on the edge of the ravine. Captain Laidlaw and submarine "Dsrw" pilot McBride - who is also Collins' lover - attempt a rescue. They dock with the pod and rescue Collins, but the unstable hatch door closes on Laidlaw. Mortally wounded, he floods the compartment, forcing McBride and Collins to return to their "Dsrw" submarine and leave without him. The remaining crew now prepare to abandon the base "Deep Star", but the missile platform must first be secured. Without Laidlaw, facility technician Snyder is forced to interpret the unfamiliar protocol. When prompted by the computer to explain the reason, Snyder reports "aggression" (due to the creature). The computer jumps to the conclusion that an enemy military force is attacking and advises the humans to detonate the missile warheads. Snyder complies and the resulting nuclear explosion creates a shockwave that damages DeepStar Six and the cooling system for the base's nuclear reactor.
