"I need to know who Red Coat is," she says in the trailer. "She tried to kill all of us."
The girls are also still receiving creepy text messages from A of course, but there's one new twist the fourth season promises to reveal. It looks like we get to finally find out who (or what) is in the trunk of Walden's car.
And another things for sure: the girls are sticking together through it all! Liars unite, right?
Pretty Little Liars season four premieres June 11 at 8 p.m. on ABC Family.
