It’s 1996, and high schoolers Isabel Castillo, our narrator, and Amy Polk are best friends—even though they couldn’t be more different. Isabel is timid and dorky, while Amy is popular, cool, and loves horror movies. In the first episode, Amy convinces Isabel to play a new touchtone, choose-your-own adventure horror game called The Haunted Orphanage over three-way calling. There’s a $10,000 prize for whoever can make it all the way through the game. Amy thinks Isabel will be good at it because she’s partially blind and has sensitive hearing. But she ignores all of Isabel’s advice during the game and, when a Pale Man appears in the game, Amy presses 1 to to take his hand. Isabel hears Amy scream, then the line goes dead.

Isabel is determined to find her friend, especially since no one else seems that worried. Amy is a prankster, and even her own mom thinks this is just another hoax she’s pulling. Only JAVI MATA, the biggest loser in school, is willing to help her. Together they start an investigation that will uncover dark secrets about their town, and put them all in danger.
