The world is turning upside down on Halloween.

Season two of Stranger Things will make its debut on Netflix on the spooky holiday.

The release date was announced in a Super Bowl spot for the show, which built a cult following after its summer 2016 debut.

The show, created by brothers Matt and Ross Duffer, takes place in a small town in Indiana in 1983, just after a 12-year-old boy named Will goes missing. His friends and mom Joyce (played by Winona Ryder), spend much of the eight-episode series trying to find him. In the process, they encounter top-secret government experiments, terrifying supernatural forces and one very strange little girl named Eleven (Millie Bobby Brown).

The Super Bowl ad featured footage from a classic Eggo commercial that debuted in 1979 and aired in the ’80s. According to a description from Netflix, Season 2 is set a year after Will’s return.

“A year after Will’s return, everything seems back to normal,” Netflix said in a release. “But a darkness lurks just beneath the surface, threatening all of Hawkins.”
