"In 1987 three teenage girls - Tiffany Clark (Liana Liberato), Marisa Song (Stephi Chin-Salvo) and Heather Hernandez (Anna Diaz) - were murdered on their sixteenth birthday by a serial killer (aka the 'Sweet Sixteen Killer'). Each victim was stabbed sixteen times. The killer was never found and only their friend Pam Miller (Olivia Holt) survived. Now, thirty-five years later, Pam Hughes (Julie Bowen) is still traumatized. On Halloween night she is attacked and stabbed to death. Later her seventeen-year-old daughter Jamie (Kiernan Shipka) hides in her friend Amelia's school project, a time machine. She is transported back to 1987, and realizes that she has a chance to stop the serial killer and prevent her mother's death in the future."

"Do the machines kill us all?"
