Truth: Sherri Griffin and her daughter, Katie, recently moved to the idyllic beach town of Newburyport, Massachusetts. They’ve been welcomed by Rebecca Coleman, unofficial former leader of the Newburyport Mom Squad, and her teenage daughter Alexa, Katie’s new babysitter.

Truth: Alexa has time on her hands after a falling-out with her friends involving her popular YouTube channel. Katie can’t be left alone because of nightmares that don’t jibe with Sherri’s vague story about her past. Rebecca Coleman has been spending time with someone she doesn’t want people to know about just yet.
