In January 1994, the U.S. Ohio-class submarine USS Montana has an encounter with an unidentified submerged object and sinks near the Cayman Trough. With Soviet ships moving in to try to salvage the sub and a hurricane moving over the area, the U.S. government sends a SEAL team to Deep Core, a privately owned experimental underwater drilling platform near the Cayman Trough to use as a base of operations. The platform’s designer, Dr. Lindsey Brigman, insists on going along with the SEAL team, despite her estranged husband Virgil “Bud” Brigman being the current foreman.The Abyss 1989 Movie Download.
During initial investigation of the Montana, a power cut in the team’s submersibles leads to Lindsey seeing a strange light circling the sub, which she later calls a “non-terrestrial intelligence” or “NTI”. Lt. Hiram Coffey, the SEAL team leader, is ordered to accelerate their mission and takes one of the mini-subs without Deep Core‘s permission to recover a Trident missile warhead from the Montana just as the storm hits above, leaving the crew unable to disconnect from their surface support ship in time. The cable crane is torn from the ship and falls into the trench, dragging the Deep Core to the edge before it stops. The rig is partially flooded, killing several crew members and damaging its power systems.
The crew wait out the storm so they can restore communications and be rescued. As they struggle against the cold, they find the NTIs have formed an animated column of water that is exploring the rig. Though they treat it with curiosity, Coffey is agitated and cuts it in half by closing a pressure bulkhead on it, causing it to retreat.One SEAL, Ensign Monk, helps Bud use an experimental diving suit equipped with a liquid breathing apparatus to survive to that depth, though he will only be able to communicate through a keypad on the suit. Bud begins his dive, assisted by Lindsey’s voice to keep him coherent against the effects of the mounting pressure, and reaches the warhead.
