A new trailer for Peacock‘s Crystal Lake reveals more about the Friday the 13th prequel series — and unsurprisingly, the new information is rather creepy.

The full trailer, released on Sunday (the 13th), delves a little deeper into the story of Pamela Voorhees (Linda Cardellini), the mother of the Friday the 13th movie franchise’s unkillable killer. The series is set in 1971 and opens with Pam employed at Camp Crystal Lake as a “lunch lady” — until her son drowns.

“I don’t want to heal,” she tells a local cop played by William Catlett. “I want to find my son.” Pam becomes increasingly convinced that Jason is still in the woods and seems to start dissocating — at one point waking up with a very large knife next to her. Watch the trailer below.

Here’s the full description for Crystal Lake: “Pam Voorhees who has been unable to shake her grief after her young, sickly son Jason tragically drowned in the town lake almost a year before. When two strangers arrive at Pam’s door digging into her past, a disturbing chain of events is set into motion, leaving the townspeople of Crystal Lake wondering: just who is Pam Voorhees?”
