Based on the novel series by author Caroline Kepnes, You follows Joe (Penn Badgley), a seemingly mild-mannered guy who forges a series of intense, stalker-like relationships with the women that cross his path.
Throughout three series, his habit of cultivating toxic traits sees him use tech and social media to freak out his various female obsessions, with the show’s fourth season finding him living in London under a new identity and ready to do more of the same.

Part one of the show’s fourth edition made its Netflix debut on 9 February, with the second half airing from 9 March.
However, fans have been wondering why Ortega, who joined the show in series two as the mysterious Ellie, a teen with an unusual friendship with Joe, is nowhere to be seen.
Why isn't Jenna Ortega in You season 4?
"I was devastated. Easily one of my favourite sets that I've ever, ever been on,” Ortega told Entertainment Tonight, citing scheduling clashes with her hit show Wednesday as the reason behind her absence.
"I was so devastated,” she continued. “I miss Ellie, and I've been wanting to go back to Ellie for a long time, but I was in Romania shooting Wednesday.
"I couldn't travel back and forth with the pandemic and everything like that, and when you're committed to a show there's just no way that it could've worked out.
"But that one, that bummed me out,” she said, adding: “I tried."
Meanwhile, showrunner Sera Gamble hasn’t ruled back welcoming Ortega back for future seasons, suggesting that anyone who isn’t dead is “fair game” for Joe’s future obsessions.
"It's been just such a pleasure to see Jenna this year. We have ideas for Ellie if her schedule allows her to visit us again,” Gamble told Indie Wire.
"Any character who's not dead who knows anything about Joe, it's fair game to try to exert any justice," she told the outlet, cryptically adding that "any character who is dead, [Joe] has a really active imagination”
Ortega has had a big year so far. In late 2022, she starred in Tim Burton’s macabre teen-tale Wednesday, a series based on the fan-favourite Addams Family character that featured a dance sequence that set social media alight.
That said, the 20-year-old star recently opened up about the intense demands of perfecting the role.
"It was show up to set two hours early, do that 12- to 14-hour day, then go home and then get on a Zoom and have whatever lesson that I had,” she told Variety.
"Or show up to my apartment, [and] my cello teacher was already waiting for me. It was just constantly going, and if you could on a weekend, if we weren't shooting the sixth day that week, it was: 'All right, well then, we'll get your lessons in on that day.'
"I did not get any sleep.”
While Netflix recently confirmed that Wednesday will return for a second series, Ortega can next be seen going up against Ghostface for a second time in Scream VI, released 10 March.
