In a small town where everyone knows each other, something unreal happens. Only yesterday the young protagonists were playing video games, and already now children see another world in front of them. After returning home, the mother of one of the main characters named Will sees that her son behaves differently. The boy became withdrawn and all the time draws scary pictures. She takes her son for a medical examination, but it does not give any results. The medical staff and scientists who were approached by the main character's mother did not explain what was happening with the boy. At the same time, one of the scientists who work in this laboratory is attacked by a mystical creature. The city's police are spending all their forces on finding the person who broke into the laboratory, but the work of the cops is inconclusive. That's why Will's mom together with his friends and one of the cops are conducting their own investigation, which leads them to a strange girl named Eleven. She's telepathic and can transmit minds from a distance... Stranger Things: Season 2 Ultra HD has become a worthy continuation of the mystical story, for which received as much positive feedback as the first season of the series.
