Stranger Things 4 opening sequence shows Eleven’s madness, hints at a bloody season

Set in 1979, the eight-minute footage begins with Brenner’s daily morning routine and the way he kept his test subjects at the laboratory, most of them unaware about the doctor’s intentions.

Doctor Martin Brenner conducts his routine tests on an inmate named Ten, who has the power to see things which aren’t in front of his eyes. The doctor asks him to find out what one of his colleagues is up to. Ten reveals she’s experimenting on Six. He eventually gets a vision of the duo screaming and dying due to something.

The high point of the sequence is when Brenner starts hearing noises and people shouting in his laboratory. Soon, the door of his room breaks open and hits him. When he gains consciousness, we expect it is either an attack by a Demogorgon or some external force. But, Eleven appears to reveal it is she who’s behind the killing of every individual in the lab. With blood splattered on the walls and Eleven’s clothes, she leaves us wondering whether she’s unable to contain her power or has attacked the lab knowingly.

The footage reveals Eleven’s backstory and hints at how she escaped the clutches of Doctor Brenner. As a test subject, Eleven was trained to make contact with the Demogorgon, and she opened the portal to the Upside Down, unleashing mayhem on Hawkins.

Stranger Things Season 4 will have Winona Ryder, David Harbour, Finn Wolfhard, Millie Bobby Brown, Noah Schnapp, Gaten Matarazzo, Caleb McLaughlin, Natalia Dyer, Joe Kreery and Sadie Sink reprising their roles.

The first part of the series will drop on Netflix on May 27 and Vol. 2 of the fourth season will release on July 1.
