In the slasher movie Halloween (2018), a vehicle carrying mentally disabled people including Michael Meyers flipped over the side of the road. They all ended up scattered all over the road. After the incident, Sheriff Barker showed a package to Hawkins:
Sheriff Barker: It's a hospital gown.
Sheriff Barker: Get on the phone to Smith's Grove. Confirm the match.
Hawkins: You know I was there that night. You know. I was there.
What "night" is Hawkins referring to?
