Complete story — includes the ending
Owens takes Eleven to an abandoned ICBM silo in Nevada, where he and Dr. Brenner have developed a specialized isolation tank (called "NINA") that will allow Eleven to access memories of her time with other kids at Hawkins Lab. After her first time in the tank, Eleven tries to escape and briefly regains her powers in the process, convincing her to continue the experiment. In California, before dying, Agent Harmon gives the kids a pen containing a phone number for Project NINA that connects to a modem; Mike decides to enlist the help of Dustin's girlfriend, Suzie, in Salt Lake City. After Yuri's betrayal, Hopper is imprisoned along with Antonov. While flying to Russia, Joyce and Murray subdue Yuri and crash in the taiga. Max, Lucas, Steve, and Dustin reunite with Nancy and Robin and investigate the Creel house. Inside, they encounter flickering lights, which they attribute to Vecna's movements in the Upside Down. Jason and his teammates locate Eddie attempting to escape in a boat on Lover's Lake; Jason and Patrick swim after him. In the water, Vecna kills Patrick in front of Jason and Eddie.
