The UAC (Union Aerospace Corporation) facility on Phobos is a secretive research base that serves as both a scientific laboratory and military outpost. It houses the Gates, experimental teleporters that create links between Phobos and Earth. The base is designed for high-security research, combining civilian scientists with military personnel to manage the teleportation technology.

The Gates are experimental teleporters developed by the UAC that link Phobos to laboratories on Earth and a Nevada base. They represent the core of the facility's mission and were intended for potential planetary colonization. When the Gate goes offline and demons invade, the Gates become the central threat, their continued operation risks unleashing a full-scale demonic invasion on Earth.

Dr. Malcolm Betruger is the film's primary antagonist, an ambitious UAC scientist who seeks to use the Gates for planetary colonization regardless of the ethical costs. He manipulates the mission, kills colleagues who oppose him, and actively works to keep the Gate active even as demons overrun the base. His moral compromise drives much of the film's conflict and represents the dangers of unchecked scientific ambition.

Setting the story on Phobos, a remote Martian moon, places the action in a isolated, high-stakes environment far from Earth's help. This location emphasizes the vulnerability of the characters, cut off from rescue and with limited resources, as they face an otherworldly threat. The sci-fi setting also grounds the supernatural invasion in technology, linking the demonic forces to the Gates experiment.
