'Pretty Little Liars' Season 6 Spoilers: Rosewood High Bans the Liars From Their High School Prom

The last week's showing of ABC Family's hit teen drama TV series "Pretty Little Liars" Season 6 revealed that Rosewood High School banned the Liars from attending the prom for security reasons. However, this won't stop them from having the best night of their high-school lives.

The report from International Business Times cited the synopsis for this week's episode titled "Last Dance." It said that the Rosewood school is quite determined to keep Alison (Sasha Pieterse), Aria (Lucy Hale), Emily (Shay Mitchell), Hanna (Ashley Benson) and Spencer (Troian Bellisario) off from its grounds during the event.

Rather than take it as a defeat, their families brew up a plan to make the best out the bad situation. They will turn the circumstances by holding a "home prom" in Spencer's barn.

The Liars are at first reluctant to the idea. Realizing that they have no other choice in this situation, the PLLs decided to go along with the home prom plan. Moreover, they should also be safe from the grasps of "A." Or are they?

The synopsis adds that Charles DiLaurentis "has other plans in store to make this night" a night that the girls "will never forget."

What could be his plans this time? If fans can remember, Charles saw placing needles in the trunk of a vehicle. IBT sounded off their speculations by saying that with the presence of the needles, it seems like the tormentor is aiming to drug the girls and kidnap them again. And where should he keep them given that his "Dollhouse" had already been ransacked by the police?
