2. The Indie Documentary Concept: "The Lost Tape of the Star Sisters"

The video appears to be a mundane home movie of three sisters at a park, but upon closer inspection (and audio enhancement), the investigator hears a coded message being whispered by the youngest sister.

The file ".mp4" isn't a movie; it's a hidden memory log recovered from a black market drive. Erin watches the video to find her "Sisters" (1 and 2) only to realize they were deactivated for being too human.

A private investigator is hired to find a missing woman, and the only clue is an encrypted file named "Erin Star - Sister 3.mp4."
