This is an indie sci-fi film about traveling around the multiverse through a magic mirror. There are many shots in mirrors in the film with one final scene with an infinite mirror.

Four tech workers sharing a house discover a hidden room in their attic with a magic mirror that serves as a portal to other universes, which are all slightly different from theirs. They all have doubles in the universes who look the same, but have had slightly different experiences. They explore the other universes, bringing back technology and knowledge to their universe, until the consequences become violent and dangerous as people from other universes begin traveling through their mirror portal.

At the end of the film, after several people from various universes are killed, Leena (Georgia King) and Devin, who she has become involved with, smash the magic mirror then get in a car and drive, hoping to leave the madness behind them. They stop at a gas station where she goes into a restroom with an infinite mirrors effect. As she stares at herself, we hear a loud surge of electricity, which is the sound we have heard throughout the fillm when someone moves from one universe to another through the mirror. She stares toward the camera, but we never see exactly what happened. Then we see her leaving the store in a store security mirror. When she gets back to the car, the scene looks slightly blurry. When someone from one universe is in another, the camera shows them as slightly blurry, and that's how she looks. Devin asks her what she wants to listen to, giving her a choice. She says she hasn't heard one of the bands in a long time, and he stares at her. She says "What?" He tells her they just listened to the band an hour ago. She says she spaced out, and they drive away. Apparently, in some way we are not shown, using another portal that is not their mirror, one of the Leenas from another universe traveled into the bathroom, got rid of the other Leena, then gets in the car with Devin, showing us that the insanity is not over.

The mirror scene starts at around 1:36:15.
