A group of astronauts on a space mission discover a derelict spacecraft orbiting a distant planet. Inside, they find a mysterious artifact that emits a strange energy field. As they study the artifact, they realize it is a portal to a parallel dimension where the laws of physics are distorted and reality itself is warped. The artifact, they learn, is a beacon for a malevolent entity that feeds on the energy of other dimensions, seeking to consume their reality. The astronauts must find a way to destroy the artifact and prevent the entity from breaching their dimension, even if it means sacrificing themselves to save their world.
