"Stranger Things" captivated audiences at the San Diego Comic-Con on Saturday, July 22 with the first trailer for season 2. The boys, Dustin (Gaten Matarazzo), Mike (Finn Wolfhard), Will (Noah Schnapp) and Lucas (Caleb McLaughlin), seem to live normal lives, playing an arcade game, until the fun is interrupted by Will's scary vision of giant, spider-like monster.

Set to Michael Jackson's "Thriller", the video sees the boys dressing as Ghostbusters on Halloween. Their trick-or-treating turns into a real nightmare when a "Ghostbusters" trap is shaking and pops open, leaving the boys spooked.

Meanwhile, the creepy visions keep haunting Will, who channels it into drawings of what looks like a monster. His concerned mother Joyce (Winona Ryder) accompanies him as he undergoes some sort of treatment, while Jim Hopper (David Harbour) is investigating the strange happenings. "Hopper gets to do some really thrilling, sexy things in season 2," Harbour said at the Comic-Con panel.

There's also a look at a new character, Bob (Sean Astin), who will be Joyce's new love interest. The video ends with a glimpse of Eleven (Millie Bobby Brown) who appears to be trapped in the Upside Down and tries to escape.

"Stranger Things" season 2 will premiere October 27 on Netflix.
