Hello, Wisconsin! It's 1995 and Leia Forman, daughter of Eric and Donna, is visiting her grandparents for the summer where she bonds with a new generation of Point Place kids under the watchful eye of Kitty and the stern glare of Red. Sex, drugs and rock 'n roll never dies, it just changes clothes.
A sheriff takes in a young child that she finds near the site of a mysterious accident. The girl has no memory of what has happened. The investigation draws her into a conspiracy larger than she ever imagined, and the child's identity is at the center of it all.
