A crew aboard a space station finds itself alone after a scientific experiment causes the Earth to disappear. When a space shuttle appears, the space station's crew must determine if it is carrying friends or foes. Orbiting a planet on the brink of war, scientists test a device to solve an energy crisis, and end up face-to-face with a dark alternate reality.
In the near future, there is an energy crisis on Earth. The Cloverfield Station with a multinational crew will test the Shepard particle accelerator expecting to generate energy for all countries solving the energy problem. However, the experiment goes wrong, damages the station and opens a portal to another dimension with a parallel Earth. They also find a woman entwined with wires behind a bulkhead of the station and they learn she worked in an identical Cloverfield Station in another dimension. Now the scientists need to find a way to return to their own dimension.
