If you loved American Horror Story 1984, you'll die for this new thriller mashup of Agatha Christie's The A.B.C. Murders and Riverdale in which a game turns deadly with a killer who picks his victims one by one, letter by letter.

Every year the senior class at Lincoln High plays assassin. Lia Prince has been planning her strategy for years and she's psyched that not only does she finally get to play, she's on a team with Devon Diaz. But this year, the game isn't any fun--it's real. Abby Ascher, Ben Barnard, and Cassidy Clarke have all turned up . . . dead. Can Lia stop the ABC killer before he reaches D?
