"The Event Horizon" was a secret government project capable of conducting long-distance flights at superluminal speeds. To accomplish this, it created an artificial black hole and used its colossal energy to distort space-time in such a way that the initial and final points of travel overlapped.

However, when the rescuers arrive at "The Event Horizon", they discover that its entire crew is dead. Special effects that create an atmosphere of horror and tension fill every scene of the film.

What happened to the ship in another dimension is not explicitly shown in the film, creating a sense of mystery and uncertainty. The characters encounter strange sounds, screams, ghosts, and their own fears.

"Event Horizon" is a cumbersome mix of science fiction and horror, which raises questions for the viewer about the nature of reality, the possibilities of scientific progress, and its potential dangers. The film poses questions about the nature of reality and how far humanity can go in its desire to conquer space.
