Note: There are spoilers in this.
The script begins with a narrator talking about the town of Riverdale, and how it isn’t what people think. We are shown what may be familiar locations, the city hall, the cinema, Pop’s Chok’lit Shoppe Diner, but also derelict buildings with boarded up walls, graffiti and meth addicts. Because this is the real Riverdale, all of it, folks. This isn’t just Archie the TV series. It’s Betty & Veronica Mars.
It starts with the death of Jason Blossom, Cheryl Blossom’s twin brother and doesn’t stop. This is a Riverdale with kids who talk about Rainbow parties, a Reggie who gets badly drunk, a Riverdale of strip joints, and, yes, a just-16 year old Archie sleeping with his music teacher and then using it to blackmail her. And suggestions of twincest too.
