In 1999, a group of friends is rocked by the sudden death of one of their own. Twenty-two years later, their daughters are pushed together by a mysterious foe.
In the wake of Spirit Week, Imogen unearths long-buried truths on her path to unmask the mysterious “A.” After Sheriff Beasley closes in, Noa, Faran, and Mouse weigh their options, while Tabby works to recover vital evidence.
As Imogen and Tabby dig into the mystery surrounding Angela Waters, Faran deals with the scars of her past. After Shawn confronts Marjorie, Noa questions her relationship with her mother, while Mouse spots a familiar face on her first date.
As the Millwood carnival approaches, Mouse and Tabby each struggle with secrets, and Noa notices Shawn isn’t himself. Meanwhile, Imogen considers her baby’s future, and Faran confronts everything that’s been plaguing her.
The friends work together to uncover Imogen and Tabby’s assailant during the Annual Thanksgiving Millwood High Blood Drive. Later, Sidney confronts Tabby about her secrets.
Despite coming clean about “A,” the friends find their troubles are far from over – especially as the results of the group’s clandestine blood drive push Tabby towards a new suspect.
As “A” doubles down, the friends must work quickly to uncover the link between Angela Waters’ death, their mothers, and their mysterious foe… before it’s too late.
Still shaken from her encounter with Bloody Rose, Mouse searches for the real Rose Waters. Meanwhile, Imogen keeps tabs on Dr. Sullivan, Tabby works on a new short, Noa takes a much-needed day off, and Faran’s strength is put to the ultimate test.
After discovering that Kelly's church is using her former home for their disturbing "Hell House", Imogen springs into action, while Mouse and Ash plan a Pride pool party in protest. Later, the PLLs' plan to freak out the faithful takes a frightening turn.
