Tonight's episode of ABC Family's hit thriller "Pretty Little Liars" is going to be a total game changer. The show's executive producer Marlene King and stars Shay Mitchell and Sasha Pieterse all dished about the upcoming summer finale and finally coming face to face with "A."

King and Mitchell sat down with Entertainment Tonight to give fans the rundown of what they can expect to see on the finale.

"All of your questions will be answered," King told Entertainment Tonight. "There's nothing left to answer-well there's one thing but I'm not gonna tell you about it."

Mitchell, who plays Emily Fields on the show, started listing off some of the more mysterious plot twists that viewers have been impatiently waiting to learn more about, .

"Who 'A' is, who 'Red Coat' is, who 'Black Widow' is, why Allison got his, how she got hit, who hit her..." she said. King picked up where Mitchell trailed off.

"Who killed Bethany," King added. "It is truly the answer episode and after tonight, we are literally on the highest cliff of all cliffhangers and we'll plunge right into the water next week and answer everything."

King also confirmed, one last time, that viewers will get the episode that they've been so desperately waiting for.

"On August the 11th, you will find out who 'A' is," she said, addressing the fans. "You will recognize this person, you have seen this person before, it's not a stranger to your world."

Pieterse, who plays Allison DiLaurentis on the show, said she was more surprised about who "A" is than she was when she learned about who 'Black Widow' really is, according to Entertainment Weekly.

 "Definitely 'A,'" Pieterse told EW. " I think Black Widow is also a shock, but when you find out who 'A' is and everything that's happened, it makes sense."

Pieterse also said that she thinks fans will be pleased with all the information they'll be given in tonight's episode, MTV reported.

"What I really appreciate about this episode is that we're not just throwing you things, so that you guys are satisfied," she told MTV. "There's actually a really deep, dark story line here, and you're seeing a totally different version of everything that has happened so far. It's this crazy person's life, and it shows what's making this character tick and why all of this madness has happened. And it's actually kind of heartbreaking."
