Every Connection to ‘Pretty Little Liars’ in the ‘Summer School’ Reboot

Over the years, the Pretty Little Liars franchise has engrossed fans with complex secrets, murders and shocking reveals.

The original teen drama, which aired from 2010 to 2017, followed a group of teens being tormented by an anonymous person known as A. Based on the books written by Sara Shepard, the Freeform series quickly garnered enough interest to earn several spinoff shows, including the short-lived Ravenswood and The Perfectionists.

In July 2022, a new iteration explored a friend group trying to track down why a stalker was suddenly obsessed with each of them in Pretty Little Liars: Original Sin.

The HBO Max series, which was created by Riverdale's Roberto Aguirre-Sacasa and Chilling Adventures of Sabrina's Lindsay Calhoon Bring, introduced viewers to Bailee Madison, Chandler Kinney, Maia Reficco, Zaria and Malia Pyles as the main characters.

Bring promised that fans of the OG series would see callbacks to PLL in the reboot. "I'd be remiss to say to not pay attention to our horror eggs and our original PLL Easter eggs," the screenwriter explained to Entertainment Tonight that same month. "If you're a fan of the original PLL, I think you will and hope you will love the Easter eggs that really kind of start in earnest about halfway through and push on to the end."
