Who killed Toby's mother? Who hit Alison in the head with the rock the night she went missing? Who is Red Coat? Who killed Bethany? Who is the Black Widow? Why has "A" been targeting the PLLs all this time? After years of torture and endless questions, Alison, Aria, Emily, Hanna and Spencer finally come face to face with their tormentor and learn the story of how and why Charles became "A."

There are mixed emotions in the DiLaurentis household when Charles declares he is coming home for his birthday. Mr. DiLaurentis (recurring guest star JIM ABELE) wants to quickly get out of town to hide Ali and Jason (recurring guest star DREW VAN ACKER) from their brother, while Jason sees this as an opportunity to finally validate all of the early childhood memories he has of "Charlie." The PLLs are just as torn, with Spencer and Hanna thinking this is the best chance they have to capture Charles, while Emily and Aria want to stay as far from him as possible. Will Jason be reunited with his brother, or is this just another trap from "A"? Meanwhile, Mona is shutting out Mike (recurring guest star CODY ALLEN CHRISTIAN) and Hanna gets an unwelcomed surprise.
