A new girl, Leah Parker, moves to Hawkins, a small Midwestern town in Indiana. She is strangely linked to many of the horrific events that took place in this town after and even PRIOR to 1983. She knows many secrets and aims to bring down Hawkins National Laboratory and eventually MKUltra itself. She is the same age as Nancy and Jonathan but works at Hawkins Police Department alongside Chief Hopper instead of studying and develops a friendly relationship with the 5 kids: Mike, Dustin, Lucas, Will and especially Max. Jeffrey, a retail clerk working at Melvald's General Store with Joyce Bryers, shows her around and is the first one to discover her long held secret.
