Season 0 of Crown Lake premiered on 2019-07-06.

Behind the polished doors of Crown Lake Academy is a world of deceit and gossip, where Eleanor's only ally is an old diary.

With school back in session and a new girl on campus, it's Nellie's turn to act as "Heather." Will she give in to tradition or break the rules in an effort to wipe the tattle wall -- and Crown Lake's notoriety -- clean of its infamous history?

Twenty five years later – 2022: When new girl Molly starts at Crown Lake, she hears whispers of a bully who used to wield power over the students with nothing but a mysterious journal. It’s considered a wives’ tale now; anyone who knew the real story long ago graduated. But when Molly finds one of those journals wedged in her room, she has to figure out…who is Heather? Why did she disappear? And what does she want? Molly is introduced to this exciting new world through her roommate, Ariadne, the youngest of three sisters who all go to Crown Lake. As Ari shows Molly the ropes, and the two try to put together the mystery of Heather, they find themselves in increasingly dangerous situations.
