It begins with an extended scene as Beverly goes back to her childhood apartment in Derry, looking for her father. An older lady answers the door, telling Beverly her father passed away. The woman invites her to come in and have something to drink. She looks around the apartment, and finds a postcard she was given by Ben as a young girl, smiling as she reads the inscription: "Your hair is winter fire, January embers."
What Beverly doesn't notice is the older woman is taken by an unseen force, and then reappears, presumably taken over by Pennywise.
"It's so hot you feel like you could die," the woman says. "You know what they say about Derry? No one who dies here ever really dies."
Then there's a long pause, as the conversation gets creepier and creepier. The woman reveals a sore on her chest. Beverly looks at a family photo from the old woman, who tells her the father used to work at the circus. She's startled to notice the picture has a human-looking version of Pennywise's face – and soon the woman, naked, is chasing her.
After the extended scene, there are a lot of shots, including Pennywise floating over a carnival with red balloons and the adult versions of the Losers Club assembling.
