Tired of being harassed by "A," the girls decide to put a stop to the anonymous emails and text messages by blocking all unknown users. But even with the mysterious ghost no longer looming over their heads, the girls' problems are far from over. With a surprise visit by a father, a surprise gift from a prospective paramour, getting some unwanted advice and an undeserved scholarly accolade, the girls' lives continue to get more complicated by the day. And after dealing with all of that, did the Pretty Little Liars really think they could keep "A" away forever?

Trying to ignore "A" backfired for the girls, and now they must pay the penalty. Whether it's a family in crisis, parental praise for an undeserved honor looming over their heads or wearing totally unfashionable scrubs while working off a debt – the girls must deal with it all. And on top of that, "A's" lipstick message is still haunting them. Meanwhile the girls must also deal with typical teenage drama – the boy kind – when a new boy arrives and pushes the status quo, a secret love is tested, a new romance blooms and an old romance is floating in the grey area.
