The official trailer for new Netflix documentary Don't F**k With Cats: Hunting an Internet Killer - and it's looks like an absolutely chilling watch.
The docuseries details the real-life crimes of Canadian killer Luka Magnotta, who filmed himself torturing animals and posted them online, and the Internet community who went on a manhunt to find him.
Arriving on the streaming platform on 18th December, the story is one of the most messed up we've heard - but the beauty of the series comes from those who vowed to track down the sadistic murderer.
The docuseries examines the stomach-churning reign of Magnotta, who first achieved notoriety when he posted a video of himself cruelly killing two kittens in 2010.
He later posted another video, which showed a kitten being eaten alive by a Burnese python, which he grossly titled 'Python Christmas'.
Later, Magnotta moved on to murder and dismemberment Chinese student Jun Lin, who he met on a gay Internet dating site, which he videoed and also posted on the Internet.
The sick killer then packaged up his body parts and sent them to various schools and politicians in his native Vancouver.
What occurred next was an International manhunt, as the then-30-year-old fled Canada.
In the trailer, several social media users tell of their quest to take down Magnotta and how the internet's global search for him began.
Three different members of the internet community that joined the manhunt can be heard speaking at the beginning of the clip and one starts with: "The internet is boundless, there's the happy places and then there's the other part of the internet, the seedy underbelly.
"I was on Facebook one day and found this video I press play and it was the worst video I've ever seen. It needs to be stopped immediately.
"People went nuts so we started looking, he could have been anywhere in the world. This person wants to play a game of cat and mouse and I'm up for that," another added.
The two-minute long teaser ends with one of the Facebook users explaining: "In the seedy underbelly of the internet, there's an unwritten rule, 'rule zero - don't f**k with cats'."
Chilling.
Magnotta was eventually caught by police in an Internet cafe in Berlin, where he was looking at photos of himself on Interpol.
The video was shared on Netflix's official Twitter account alongside the caption: "What happens when a video gets posted of a shadowy figure killing kittens? The internet goes full detective.
"As this true story unravels, one thing's clear: DON'T F**K WITH CATS."
Don't F**k With Cats: Hunting an Internet Killer hits Netflix on Wednesday, 18th December.
