When a group of outer-city Baltimore teens in Harbor's Point, begin receiving anonymous texts exposing their darkest secrets, the line between guilt and survival blurs. Each message ends the same way: "I know what you did last spring. 1984 never forgets." As the messages turn deadly and bodies start dropping, Zach O'Connor becomes the reluctant final boy in a nightmare where the past won't stay buried-and the killer is much closer than anyone thinks.
