Mr. Soul (2006)

A serial killer preys on prostitutes from the mean streets of a small, mid-west city as the police turn a blind eye. With an insatiable sexual appetite, the killer brutalizes his victims and leaves their bodies at Moon Lake outside of town. A voice inside the killer's head commands him to kill, his victims beg for death. John Martin Crawford is only too happy to oblige. But Moon Lake happens to be a spiritual holy ground for the local Native Americans, and soon the victims' ghosts are haunting both family members and complete strangers in desperate pleas for justice so their souls may rest. A supernatural story that reminds us the dead are not powerless.
