Pretty Little Liars Season 4 is only a little over a month away (it premieres June 11), and the first real promo is already out. This video is overflowing with clues, so of course we took a very close look to figure out what we could discover about the upcoming season.

What's in the trunk? Obviously this promo doesn't answer that question, but it does call it a "terrifying discovery," and shows a clip of Emily in tears. We also hear someone say "She set us up," which isn't good.

Aftermath of the fire. At :05 we see a fireman picking through a burned building (presumably the remains of the fire in the Season 3 finale). He's holding a charred red coat. It also looks like we might get to see inside the burned building at :12.

Toby in the woods. Who is Toby spying on at :05? Is it the fireman?

Aria breaks down. At :06 we see Aria flipping out in a car. She looks angry. Why?

The Liars and Mona. Throughout the promo, we see Mona paired with the Lairs. It seems they are all working together. Why? Well, at :11 Mona tells the Liars, "I need to find out who Red Coat is. She tried to kill all of us!"

Trailer park and the lair. At :06, the Liars and Mona (in a black hoodie!) are in a trailer park. We wonder why. Could that be where "A"s mobile lair is parked? We're thinking yes, because at :07 we see all of the Liars in said lair, looking through a computer.

There IS a body. Or so it would appear at :08, where it looks like there is a body bag.

Broken mask: At :11 we see a broken mask that appears to be under water. We think it's in a pond or lake or something, because there seem to be rocks next to it.

The pool. We know there's a Pailey pool scene coming up, and we get what's probably a flash of it at :11.

Near car accident. Yup, looks like there is another near-fatal vehicular problem at :12.

Funeral? At :13 we see all four Liars in black (and later Mona in black, too). Are they going to a funeral? We're betting so. Not only are they in black, but they're dressed nicely and it's the middle of the day.

New threats. The texted threats aren't over yet. The Liars and Mona get this message: "The truth won't set you free, I'm going to bury you with it. — A." Later, a clip from the same scene shows Emily getting an alert, saying "Oh my god," and then showing the other Liars something on her phone.

Aria gets close with her karate instructor. At :19.

Aria running with tears. Why is Aria running through a hall with tears on her face at :20?

Check it out for yourself.
