In 2005, Alex lives in a village with his mother Klara and his cruel, unloving father Björn. Klara finally leaves the family, Alex's closest friend Anna moves to Stockholm, and Alex moves in with his uncle. Ten years later, Alex has become a famous musician in Stockholm. During Midsummer, the city is struck by multiple explosions, one of which kills his mother. Alex splits with his manager and goes back to his home village to buy the church piano that he and Anna used to play when they were younger. There, Alex again meets Anna, who has moved back to the village. When he learns that she has a husband, Kim, and daughter, Elin, he angrily departs. As attacks on Sweden worsen and the military is activated, people begin crashing their cars in the rain and Alex returns to help Anna and her family. After the Parliament is destroyed and communications networks become unavailable, Anna's mother, a government minister, manages to escape Stockholm and heads into the country, where she is rescued by the military. Meanwhile, Alex's father Björn, who works at a transformer station, kills a group of armed men who are attacking the electricity network. Helicopters and dead birds crash to the ground, apparently affected by contaminated rain, and civilians come to the station seeking safety in its bomb shelter. Among them are Anna and Alex, who is injured and unconscious. After Anna leaves in search of Elin, Alex comes to and tells his unapologetic father that Klara is dead. Anna returns with her daughter and tells Alex that her husband and many others were killed by helicopters. However, Kim is in fact alive. When helicopters approach the power station, the civilians head to the village church to meet the military, whom they have contacted by radio. The enemy attacks the military and kills Anna's mother, but Alex destroys an enemy helicopter by crashing a car into it and Björn takes down another helicopter by crashing his plane into it. He dies but saves Alex, Anna, and Elin. In the village church, which has been destroyed and is on fire, Alex tells Anna that Kim is still alive, then plays the piano until he loses his memory due to chemical weapons in the rain. Anna is taken away by Kim. News clips during the credits indicate that 800,000 Swedes have lost their memory, and images of
Vladimir Putin suggest that Russia was behind the attacks. == Cast ==
