The Liars are back! Not the original ABC series Liars, but a whole new generation within the same universe, and they're coming to HBO Max. The Max original series Pretty Little Liars: Original Sin will premiere its first season on July 28, releasing the first three episodes, and they've just unveiled the official teaser trailer.

Miles from the town of Rosewood, in the blue-collar Millwood, someone is stalking the brand-new liars. Twenty years after tragedy threatened to upend the town, an anonymous Assailant is out for revenge. Targeting the teenage daughters of those who committed the original sin, the stalker torments the girls as payment for what their parents have done. The distressed teens may discover that this mysterious avenger, A, knows more about their own dark secrets, as well.

The teaser reveals a sinister lurker who possesses images and personal belongings of the Liars. In a darkly-lit basement, the mysterious, gloved A pins photos and police documents to the wall, producing undeveloped film of the girls and an alarming MISSING poster of a teenage girl dubbed Minnie "Mouse" Honrada, oddly reminiscent of Alison DiLaurentis (Sasha Pieterse). With the familiar tinkling theme song from the original series eerily playing in the background, A slices a photo of a girl and the head flutters down to a bejeweled tiara and diary entries. As the teaser shrills to its conclusion, the mysterious figure destroys the photos one by one, burning, shredding and hammering nails into them. Clearly, A is not messing around. The camera pans out to reveal a dark silhouetted person with long hair standing menacingly in their lair with a red A appearing over them.
