Archie, Betty, Jughead, Veronica and the rest of the gang are all getting ready for the next stage of their lives after high school graduation – or, at least, they're trying to. But then, one by one, they all receive a mysterious letter from someone calling themselves the Poison Pen. Somehow, the letter writer knows some of Riverdale's deepest, darkest secrets. And the Poison Pen is threatening to reveal all unless Archie and his friends do exactly what they're told – from posting embarrassing videos of themselves to blowing up someone else's marriage. The letters aren't stopping and the stakes are getting higher with each one. If they can't find the Poison Pen soon, Betty, Jughead, Veronica, Archie, Kevin, Cheryl and Toni might not have a future left to protect.
