Pretty Little Liars - The Complete Fourth Season

Year Four is a tumultuous one for the Liars beginning with the murder of Detective Wilden (Bryce Johnson) and Hanna’s mother (Laura Leighton) being charged with the crime, which isn't helped by Hanna (Ashley Benson) rash actions at a college party, and ending with the girls learning the truth that Alison DiLaurentis (Sasha Pieterse) is alive and finally getting a few answers.

Relationships are hard on the Liars this years as Spencer (Troian Bellisario) and Toby's (Keegan Allen) romance is strained first by her keeping secrets that might help her boyfriend investigate his mother's death and later by the recurrence of her pill-addiction. Emily's (Shay Mitchell) swimming future and scholarship chances will be derailed by a shoulder injury which also begins the first of many problems with Paige (Lindsey Shaw). Hanna will lose Caleb (Tyler Blackburn) to the show's spin-off. And Aria (Lucy Hale) will dump Jake (Ryan Guzman) and return to Ezra (Ian Harding) which becomes doubly-complicated when the Liars begin to suspect he might be A.

In other episodes Caleb and Toby search for Red Coat, we get a mid-season finale trip and Halloween in Ravenswood, the truth behind Ezra's lies is revealed, the discovery of Alison's encoded diary offers clues to why she disappeared, a new A suspect emerges, Spencer and Aria confront Melissa (Torrey DeVitto), Mona (Janel Parrish) makes a surprising confession, Hanna will get a new love interest (Luke Kleintank), Spencer gets used to life with a sobriety coach (Nathaniel Buzolic), and the beautifully shot black-and-white episode is the result of Spencer's speed-driven fevered mind searching for the truth.

The five-disc set includes all 24 episodes, the bonus recap episode, unaired scenes, and featurettes on Alison, A's Lair, and the costume and set design of the season (particularly the Halloween, hoedown, and black-and-white episodes).
