Pretty Little Liars Winter Premiere “Through a Glass Darkly” Synopsis

The Liars are on the offensive in Pretty Little Liars’ winter premiere, airing Jan. 6 on ABC Family.

The new episode “Through a Glass Darkly” will see Aria, Emily, Hanna and Spencer, three months after Mona’s murder, determined to definitively prove Alison killed her.

Ready to put “A’s” game to an end and get justice for Mona, the PLLs ramp up their search for evidence that could prove Alison’s guilt.

But with Alison claiming her innocence and having a seemingly airtight alibi, the Liars may have to resort to more shady tactics to put Ali away.

Meanwhile, Emily and Paige reach a crossroad in their relationship, and Aria starts to worry about her future.

The winter premiere follows an all-day PLL marathon from 12:00 PM – 8:00 PM ET/PT.
