In 'YOU' Season 4 trailer, Joe is the one searching for a killer

How the tables have turned.

Netflix just debuted the trailer for "YOU" Season 4, placing Joe Goldberg (Penn Badgley) smack in the middle of London.

The serial killer adapts the name Jonathan Moore for his new life, after fleeing California in the previous season.

Just as he's settling in his new city, a series of killings gets his attention. He begins to investigate the crimes.

He also receives a text saying: "Hello Joe. Now do I have your attention?"

It looks like Joe won't be able to run forever!

The first part of "YOU" Season 4 is set to premiere on Netflix on February 9.

Part 2 will drop on March 9. —JCB, GMA Integrated News
