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.

After joining Leroy at their new house in Derry, Charlotte is left with a strange feeling while running errands in town, and Will is teased on his first day of school. Later, Lilly faces pressure from all sides about what really happened at the movie theater, and 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.
