Three Wolves.

A video file is found on a hard drive, containing footage of a man known as "Number 3". He is suspected of having a surgically inserted "death's head" coin in his body as he is monitored by security cameras to track physical and mental changes. The coin is rumored to be forged from WW II death's head rings, said to contain the souls of the soldiers that wore them. These coins were surgically inserted into "patients" to test the efficacy of the lore.
