IT: Welcome to Derry

As four misfit kids vow to find their missing classmate, Major Leroy Hanlon arrives to a mixed reception at Derry Air Force Base.

While Charlotte and Will navigate their new life in Derry, Ronnie worries about her father's fate.

When a major find yields few clues, General Shaw pushes ahead with his top-secret mission, ordering Leroy and Pauly to escort Dick Hallorann on an aerial search for a new dig site. Meanwhile, Rose attends a tribal meeting about the military presence in Derry, and Ronnie, Lilly, Will, and Rich attempt to get visual proof by conjuring an Orixá.

After their efforts are rejected by Chief Bowers, the kids must deal with their disappointment...and a series of increasingly terrifying experiences. Meanwhile, as General Shaw escalates his efforts to find answers, Charlotte tries to advocate for a reluctant Hank, who worries his secret will get out. Urged on by the Patty Cakes, Marge pulls a mean-spirited prank on Lilly.

After learning the truth about General Shaw's operation, Leroy decides to move his family to the base for safety. While the tribal Keepers strategize how to contain increased aggression in town, the military descends on Neibolt Street, and the kids head into the sewers with their own objective.

Plagued by increasingly dark visions, Dick learns the Black Spot is integral to Charlotte's plan. Meanwhile, Will faces his parents' disapproval for walking into a dangerous situation, Marge stands up to the Patty Cakes, and Lilly's behavior grows erratic.

When a group of masked vigilantes descends on the Black Spot, the ensuing carnage unleashes long dormant forces. In the tragic aftermath, Rose and the Keepers assess their losses, Leroy vows to leave Derry, and Dick helps uncover another crucial artifact.
