A lot of craziness is in store for the girls of Rosewood on an upcoming episode of 'Pretty Little Liars' entitled 'Unbridled,' which airs on March 11. We'd expect nothing less from the penultimate episode of the season.

Read on to find out who is returning to Rosewood, who is getting back in the dating game and who is betrayed by someone close to them.

As the official synopsis for the 4x23 episode reveals:

It is a rough time for all of the Liars as Spencer is reeling about the memories from her “lost summer,” Aria is still nursing a broken heart, Emily is reeling from Paige’s betrayal and Hanna unsuccessfully attempts to wade back into the dating pool.

But as each girl tries to deal with her individual issues, they must focus their attention on their suspicions surrounding Mrs. DiLaurentis. Assuming that Mrs. D knows more about Ali and the night she went missing, girls decide to help out at her charity bridal fashion show to gain access to the DiLaurentis house to search for answers.

To sum things up: Spencer's memories return, Aria is still in a bad place following Ezra's recent revelation, Paige did something to betray Emily (NO!), Hanna is trying to date again and Mrs. DiLaurentis is being suspicious.

As if all that wasn't enough, both Jason DiLaurentis and Aria's mother Ella are making their triumphant return to Rosewood, Jason with something to hide and Ella with a secret!

Could Ella have tied the knot while in Austra with her new beau? Someone is supposed to walk down the aisle this season after all.

We'll just have to wait and see! 'Pretty Little Liars' airs again on Feb. 25 on ABC Family at 8PM ET.
