Spencer tracks down Emily and Aria in a panic – she got an alert on her phone that someone is moving Mona’s laptop. They think that Hanna went to the locker after they told her not to, and is moving it. They jump in Spencer’s car and follow the laptop’s GPS signal.
Suspecting that Alison/“A” is out to frame her for Mona’s murder, Hanna is not willing to just sit by and let it happen. Caleb and Hanna’s friends try to come up with a safe plan to get her off the hook, but it isn’t good enough for Hanna and, taking her fate into her own hands, she strikes out alone to clear her name. Meanwhile, relationships are tested when Aria comes clean to Ezra and Spencer’s shady actions continue to put Toby in a bind at work. #PLL #PrettyLittleLiars
