ABC Family to Air PRETTY LITTLE LIARS Halloween Special, 10/23

ABC Family has locked in the date for its latest PRETTY LITTLE LIARS Halloween special: Tuesday, October 23 at 8:00/7:00c.

A day-long marathon of the show's current summer run - which wraps next week - will lead into said event, part of the network's annual "13 Nights of Halloween" stunt (October 19-October 31).

Also on tap: the season finale of "Switched at Birth" on Monday, October 22 at 8:00/7:00c. As previously announced, "Birth" returns for its fall run on Monday, September 3 at 8:00/7:00c. A second season was commissioned last week.

On the new season of PRETTY LITTLE LIARS, the girls are ready to kick some "A." No longer just wanting to sit by and wait for "A’s" latest cruel attack, Aria, Emily, Hanna and Spencer take matters into their own hands and try to finally put a stop to their tormentor. As relationships are put to the test, new and old secrets are revealed and the stakes are raised higher than ever before as the Liars come closer to the truth - will all of their sacrifices be worth it in the end?

"Pretty Little Liars" won three Teen Choice Awards in 2011 for Choice Summer TV Series, Choice Summer TV Actress – Lucy Hale and Choice Summer TV Actor – Ian Harding. The show also won the "TV You Betta Watch" Award for 2011’s NewNowNext Awards as well as the "Cast to Watch" for 2011’s The Young Hollywood Awards.
