In 2026, mysterious and dangerous creatures from the eerie Upside Down begin invading Hawkins once again. As the threat grows, Mike Wheeler, Dustin Henderson, and Lucas Sinclair realize that the danger they face is far greater than anything they have encountered before. Standing with them is Eleven (Jane Hopper), whose powerful psychic abilities may be the key to stopping the darkness.
At the same time, a group of powerful alien robots known as the Autobots arrive on Earth after detecting strange dimensional energy connected to the Upside Down. Led by Optimus Prime, they bring with their powerful allies—the mighty Dinobots, the noble Maximals, the courageous Rescue Bots, and the young Cybertronian heroes known as the Terrans.
Surprisingly, they are also joined by Megatron, who now fights alongside Optimus Prime and the other defenders of Earth.
As terrifying monsters such as the Demogorgon and the powerful Mind Flayer spread destruction throughout Hawkins, the kids and the Transformers must unite. With courage, teamwork, and extraordinary power, this unlikely alliance must face the growing darkness before the Upside Down completely consumes their world.
