In 1976, every home movie developed by Wally Splice contained the same extra man.

At first, he stood across the street. After the next cut, he was on the porch. Then he was inside the house.

When Norine Rumm's husband disappears from his own birthday film, she uncovers the rule behind Wally's movements: he cannot move while the camera is recording. He only moves in the darkness between shots.

Norine enters his shop carrying an eleven-minute reel and refuses to stop filming. But every reel eventually ends.

This fictional analog-horror story explores cursed film, disappearing memories, and the terrifying possibility that the most dangerous part of a recording is the moment the picture turns black.
