In 2047, a #distresssignal is received from the #EventHorizon, a starship that disappeared during its #maiden voyage to Proxima Centauri seven years before and mysteriously reappeared in a #decaying orbit around Neptune. The rescue vessel Lewis and Clark is dispatched to look for survivors and determine what happened. Captain Miller of the Lewis and Clark—along with second-in-command Lieutenant Starck, pilot Smith, medical technician Peters, engineer Ensign Justin, Doctor D.J., and rescue technician Cooper are also joined by Dr. William Weir. Dr. Weir, who designed the Event Horizon, briefs the crew on the ship's #experimentalgravitydrive. The drive generates an #artificialblackhole and uses it to #bridge two points in spacetime, reducing travel time over astronomical distances.
Upon boarding the Event Horizon, the crew finds evidence of a massacre. As they search for survivors, the ship's gravity drive automatically activates. Justin is briefly pulled into the resulting portal. The activation also causes a #shockwave that damages the Lewis and Clark, forcing the entire crew to board the Event Horizon. After Justin is pulled out, he is in a catatonic state, #terrified by what he saw on the other side. He #attempts suicide, forcing the crew to place him in stasis.
The team begin to experience #hallucinations#correspondingtotheirfearsandregrets: Miller sees Corrick, a subordinate he was forced to abandon to his death; Peters sees her son with his legs covered in bloody lesions; and Weir sees his late wife, with missing eyes, urging him to join her. The crew soon discover a video log of the Event Horizon's crew going #insaneandmutilatingeachother. The video log ends with a shot of the Event Horizon's captain, who has apparently gouged out his own eyes, holding them up to the camera and saying in Latin, " #liberate#tuteme ex #inferis" (" #saveyourselffromHell"). Miller and D.J. deduce that the ship's gravity drive opened a gateway into a dimension #outsidetheknownuniverse. Starck theorizes that the Event Horizon has somehow become a sentient being which is #tormenting its occupants in an attempt to kill them or lure them back through the portal.
