Everyone has a secret in Rosewood and it's only a matter of time before it is revealed. Four girls know this to be especially true and are reminded of it on a daily basis. As the police turn up the heat and make Spencer an official "person of interest," maybe the girls should take a closer look at those around them. The boy one has given her heart to may have ulterior motives; the girl they have wronged may not be as innocent as they think; and the person another likes may make a rash decision that cuts to the bone. All are things that the girls should take into account ... before "A" does. Meanwhile, Ella and Byron try to decide what the latest development in their relationship means for them and their family.
