'There are things we just couldn't tell, especially if it's a murder confession.' Doctor Astrid's current patient, Lindsey, was a survivor and a witness of a well-known cold case that brought nightmares to the whole town of Pendle. The trauma led Lindsey to become mute and paranoid, making their sessions hard to finish. However, as time passes by, Astrid slowly realizes that Lindsey wasn't mute at all, but refusing to speak-- as if there are things she can't tell.
