Two Americans, Ben and Sean, travel to Moscow to sell a piece of software. After arriving, they find their business partner, Skyler, has betrayed them by already selling a knockoff application. Disappointed, the pair goes to a nightclub and meets tourists Natalie and Anne. Suddenly, the lights go out and everyone heads outside. There, they witness balls of light fall from the sky and fade away. Invisible entities begin hunting and disintegrating people, generating panic.
Ben, Sean, Natalie, Anne, and now Skyler hide in the club's storeroom for seven days. With most of their food gone, the group leaves the club and finds the city full of scorched cars and cinders, but empty of people. While they search for supplies in a Militsiya police car, an alien appears. They hide as it moves closer, causing the car's lights and siren to turn on. This makes Sean realize that light bulbs and other technologies give the aliens away. The group takes shelter in a shopping mall. Sean and Natalie go to look for clothes and almost run into an alien who cannot see them through a glass wall. Sean theorizes that the aliens can only see their electrical charge, but not through glass or other insulators.
The group finds the US embassy gutted and lifeless. A logbook there tells them that the invasion is worldwide. They also discover a radio broadcasting a message in Russian. During their search, Skyler is killed by the aliens. The others see a light in a nearby apartment tower and go to investigate. They find a young woman named Vika and a man named Sergei, an electrical engineer. Sergei has made his apartment into a giant Faraday cage that hides everyone from the aliens. He has also developed a microwave gun that weakens an alien's force field, so that it can actually be seen and killed. Vika and Sergei translate the radio message, which says that a nuclear submarine is waiting in the Moscow River to take survivors to safety, but will leave soon.
Vika, Natalie, and Anne go to other apartments to gather supplies. An alien senses them outside the Faraday cage and gives chase. When they get to the apartment, the alien gets inside with them. Sergei shoots the alien with his gun, to no avail. The alien kills him while the others escape. Anne is also killed in the ensuing chase. To fight back, Natalie sets the apartment on fire and meets up with Vika.
The group later meets with Russian policemen who manage to wound an alien with conventional weapons. Sean collects a piece of the alien's body while the small police band agrees to help the group get to the submarine. As they move through the subway, an alien discovers them and kills Ben.
The survivors make it to a powerless patrol boat on the river and drift downstream to the waiting submarine. The boat nears the submarine, but runs aground. As they attempt to push free, an alien light beam causes the boat to capsize. Sean and the policemen swim towards the submarine, but upon reaching it, they discover Natalie is missing. Sean is determined to get her, possibly missing his chance to escape. The policemen agree to help him. The submarine crew, after expressing their doubts about the rescue, assist by building another microwave gun with stronger batteries.
Sean finds Natalie on a bus while the policemen and Vika start destroying aliens with the microwave guns. During the battle, Sean discovers the creatures' weakness when he throws a piece of the wounded alien he collected to another one, killing it. The two stop the bus and narrowly avoid a collision.
After returning to the submarine, the police team decides to stay and fight for the city. Meanwhile Sean, Natalie, and Vika plan to spread what they learned about the aliens to the rest of the world. Sean and Natalie, the only survivors of the original group, nearly share a kiss until Vika scoffs and breaks the romantic tension in a light-hearted moment. In the last scene, they learn that multiple resistance groups are fighting in different cities all around the world.
