The trailer of "Pretty Little Liars" season 4 winter premiere is out and it clears the air that the girls will not be out of the woods soon. So, what will happen in the winter premiere of season 4 episode 14 titled "Who's in the Box?"?

Initially, the girls thought that if they find Ali their problems would come to an end, but Ezra is free and quite determined.

The truth is out and fans cannot wait for season 4 winter premiere. Ali is alive and we want to see her again, perhaps, loads and loads of Ali scenes. After looking at the promo, we can say that "Who's in the Box?" will showcase Ali in a grand way. Ali is back in person and not as a ghost or scenes from the past, in person. This makes the season 4 episode 14 special.

In the new episode, the girls are trying to find out whom Ali's running from.

"Tell me who you're hiding from?," Emily, her tone sounds urgent, asks Ali.

"I thought I knew. But I was wrong," Ali replies. Certainly, these dialogues build the tension and we can expect A's sinister plan unwraps in the new episode.

What is A's plan?

Apparently, A rolls out his/her wicked trick yet again in a bid to stop the girls from searching for their tormentor. A puts his/her new message in Hannah's mouth after she is found sedated by a person wearing black gloves. Ezra is suspicious and tells Mona, "Fear can be a very good thing."

Meanwhile, Aria asks, "Who is this monster?" The girl is unaware that the answer to her question will take her to her boyfriend.

"Pretty Little Liars" season 4 episode 14 "Who's in the Box?" airs on Tuesday, Jan. 7 on ABC Family.
