Famous Swiss psychiatrist Carl Jung believed that every one of us has a shadow,

a dark hidden self made up of the thoughts and feelings

we repress, rage, shame, envy, and cruelty.

It waits beneath the surface wearing our face,

but thinking darker thoughts. Most people keep it buried.

David Berkowitz did not. In the sweltering summer of 1977, New York City was paralyzed by fear.

A faceless killer was stalking the streets. Young couples were gunned down

at random. The press called him the 44 caliber killer. Then he gave himself a name. He called

himself the son of Sam.

He left letters behind, riddled with a blood-soaked fantasy, an apocalyptic delusion.

He claimed demons spoke to him, that a dog, his neighbor's dog, was a vessel for Satan.

But when he was finally caught, Berkowitz admitted something else.

It was all a lie.

The demons, the dog. It was a performance crafted by a man who hated the world

and wanted the world to know his name.

This is the story of David Berkowitz, of the quiet boy who became one of the most notorious serial killers in modern day history,

and of the rage he could not contain and the shadow he let win.
