Joseph was a serial killer. He loved his wolf mask, which he called "Bitchface." He assumed a new identity with each victim. He often invited people to solve a problem (usually involving filming), assuming different guises. For example, a priest, a pharmacist, or a family man with cancer. The purpose of filming varied. A realistic game. But he killed the victims with an axe that same day.

However, Aaron was his most prized victim. This curly-haired man with glasses and a camera in hand was an aspiring photographer, slightly taller than him. He replaced him at his country house under the pretext of filming a video in honor of his late wife and son in a plane crash. But Aaron was no fool and put the pieces together in his head. Realizing that the axe in the stump was a hint, he left without staying the night. Joseph lured him in a second time, playing on his pity. He feigned misery and loneliness. He realized Aaron was no ordinary victim. He'd kill him and put the tape with the video (he had a collection) in the closet with the others, marking it only with a heart.

They were already in the little house. It was evening. They were drinking tea. Aaron was working on the camera. "Aaron, turn it a little to the left. I want to see the forest. My wife loved nature," he said casually. He didn't want to scare him. But then, seeing the vein on Aaron's neck, he couldn't help himself. "Aaron, can I hit you?"
