Tuesday's episode of Pretty Little Liars, part of its fourth season, has the girls check out colleges for the fall.

In the episode titled Gamme Zeta Die, Emily, Aria, Hanna and Spencer spend the weekend attending campus tours and crashing frat parties. A promo video released by ABC Family and pictures from the upcoming episode reveal that they may be a step closer to figuring out who "A" is.

Just because they are leaving Rosewood for the weekend does not mean the mysterious mastermind, "A," is far behind. Especially because it is believed that "A" has a car, since he or she has used it frequently to try to run the girls over in previous episodes.

In released pictures from the episode, Aria is shown pushing a guy away from her at a party. With her prior martial arts training from Jake, viewers wonder if she will use her skills to teach the aggressor a lesson. Hanna appears to be anti-social at the party until another party-goer knocks a snack bowl into her lap. Annoyed, Hanna remains sitting as the boy picks up his mess.

Later on in the episode the Liars visit the woods which in past episodes has not resulted in good outcomes. This time Hanna encounters two police officers shining flashlights in her face.

Pretty Little Liars is an ABC Family television series based on the best-selling book series for young adults from Alloy. When their best friend Alison mysteriously vanishes, four girls believe their secrets are safe forever. However, when they begin to receive threatening messages from someone named "A," the truth may be only one text away.

Pretty Little Liars stars Troian Bellisario, Ashley Benson, Tyler Blackburn, Lucy Hale, Ian Harding, Laura Leighton, Shay Mitchell, Janel Parrish and Sasha Pieterse.

The newest episode, Gamme Zeta Die airs Tuesday, July 9 at 8 p.m. EST.
