The movie begins with a narrator recounting a tragic event from 35 years ago in North Vernon. In October 1987, a girl named Tiffany met a horrifying end in her garage on her 16th birthday. Only two days later, Marissa's life was cut short at her family's woodland cabin. The eerie pattern continued when, on Halloween night, a third victim, Heather, was brutally slain in an amusement park parking lot. All three girls were sixteen and suffered sixteen stab wounds, earning the killer the chilling moniker "Sweet 16 Killer." Shockingly, the killer never struck again, and their identity remained a mystery.
