It is about a weird guy who is afraid of being tourned down by society moving out to the country so he can turn down society first. He then stumbles upon a man who appears to have shot himself under a tree on his new property.

He eventually ends up being guided by the ghost of the dead man to solving a local homicide, and taking on the serial killer himself. Here is the link:
