PRETTY LITTLE LIARS - "Of Late I Think of Rosewood" - After years of tormenting and numerous shocking revelations, the Liars finally uncovered the true identity of “A.” Now, five years later, the girls have each pursued her own path and have started adjusting to a life without “A,” when something happens in Rosewood that forces them to go back to where it all started, on an all new episode of ABC Family's hit original series "Pretty Little Liars," airing Tuesday, January 12 at 8:00 - 9:00 PM ET/PT.

They grow up so fast! Thanks to a midseason time jump, Season 6 of Pretty Little Liars resumes with the girls older, wiser and just as haunted as ever since the unveiling of CeCe Drake (Vanessa Ray) as their transgender tormentor, Charles DiLaurentis, aka “A.” It’s five years down the road and they’ve each had different experiences, some more successful than others,” executive producer Joseph Dougherty reveals. “They’ve moved on.”

Aria (Lucy Hale) is in Boston working for the publishers behind the first novel by her ex Ezra (Ian Harding), who is dealing with a traumatic loss; in New York City, Hanna (Ashley Benson) has a dream fashion job that may have cost her a future with Caleb (Tyler Blackburn); Spencer (Troian Bellisario) is doing nonprofit advocacy in D.C. and inspiring her mom to run for office; and Emily (Shay Mitchell) is, well, not well. “She took the roughest hit of anybody,” Dougherty says of Emily’s army dad’s death.

Ali (Sasha Pieterse), meanwhile, is the only one who stayed in Rosewood and, as the trial of her institutionalized sister—now going by Charlotte—nears, she asks the old friends to return to town. “She needs them to participate in what would be the ultimate act of healing and forgiveness for Charlotte,” says Dougherty, adding that this less-than-happy homecoming will become a nightmare once “events are set into motion that keep the girls in Rosewood” and at the mercy of the nastiest big bad they have ever encountered. “This is a level of evil,” Dougherty warns, “that has not been seen before.”
