The official trailer of You Season 4 Part 1 is out.
The hit psychological thriller follows Joe (Penn Badgely), a charming bookstore manager and serial killer, who tends to kill the women he's obsessed with. But everything changes when he falls in love.
In Season 4 Part 1, Joe starts anew in London as a literature professor under the name Jonathan Moore. It follows the events of Season 3 when he left California to bury his "messy" past and find true love.
But Joe's fresh start gets disrupted when he discovers that there's seemingly another serial killer around, who's targeting a group of überwealthy socialites (or "privileged douchebags," as he puts it) he interacts with.
Joe is also receiving creepy text messages from someone who knows his true identity, and he tries to identify and stop whoever this person is.
He's also setting his sights on a new love interest named Kate (Charlotte Ritchie), an "extremely intelligent" lady who's also "suspicious and totally cut off from people who aren't her friends."
You Season 4 Part 1 will premiere on Feb. 9, while Part 2 will follow on March 9.
