AMFAD All My Friends Are Dead (2024)

20 years after an unknown serial killer murdered seven people at a music festival with murders based on the Seven Deadly Sins, the music festival is hosted once again. A group of influencers, being made up of Sarah, Mona, Will, Liv, L.B. and Guy, plan to head to their festival; their friend Aaron is unable to come due to his job. On the way there, their car breaks down and a police officer drives them to a nearby Airbnb for them to spend the night at; however, they cannot attend the festival. Unbeknownst to them, they are being observed via hidden cameras by an unseen person.

The group finds shot glasses labelled after the Seven Deadly Sins and, after designating each glass to a group member with the exception of one, spend the night consuming alcohol and drugs. Guy, who is heavily high, leaves in an attempt to catch a ride to the music festival but is abducted by the person, a masked killer wearing an LED mask who pumps a gas into Guy's stomach until it explodes. While L.B. and Mona are having sex, with L.B. filming it, Mona sees the killer in the background of the recording. The group receives a message from someone claiming to be Collette, a former member of the friend group; Mona reveals that after she violently rejected her, Collette died of suicide by shooting herself in the cabin where the group used to spend time. Liv is kidnapped as she tries to leave and is tied under a vat of boiling water, with the killer challenging the internet to get the stream to 1000 likes; although the stream reaches the goal, Mona doesn't believe it's real and dislikes it, causing the count to go down; the killer allows the water to melt through Liv's skin.

Aaron leaves his job and begins to drive in the direction of the Airbnb. L.B. is stabbed by the killer with a bladed dildo after being lured upstairs, who then beats him to death with a baseball bat; Aaron arrives and discovers the corpse. Sarah, Mona, Will, and Aaron discover a hidden door to a basement filled with monitors, all showing Collette's face and videos of the group. Under pressure from Sarah, who doesn't know what's going on, the group reveals that Collette sent Mona a nude video, which the group uploaded to the Internet, ruining Collette's life; attempting to make amends, they headed to her cabin only to discover her dead, having carved their names into the wood. Hiding their involvement, the group burned down the cabin.

Realizing the motive for the murders, Sarah berates Mona; they find the bodies of their friends before the killer arrives, killing Will and Liv, who was badly wounded, with an axe. As they attempt to escape the basement, Mona throws down Aaron onto the killer, who stabs him to death before all three fall into the basement. Mona unmasks the killer, revealing them to be the police officer from earlier, Lois Shaw. Shaw and Mona enter a scuffle and Mona throws a knife to Sarah; however, Sarah slits Mona's throat instead. She reveals to Mona that she and Shaw planned the entire night as revenge after Shaw saved her from suicide, using the style of a serial killer 20 years prior in order to frame it as a copycat killer. Sarah allows Mona to die of blood loss before she and Shaw set up the scene to make her the sole survivor.

Some time later, police officers (including Shaw) arrive and investigate the scene. Shaw pulls Sarah off to the side as they kiss, only for Sarah to reveal one additional piece of information; having found out about Collette's torment, Sarah had lured Mona to the cabin with the intention of killing her. However, Collette intercepted the message and in the process was accidentally shot and killed by Sarah, who framed it as a suicide and blamed the friends for everything; in order to not leave any witnesses, Sarah glues Shaw's gun to her own hand and frames her as the killer, causing a detective to shoot her dead. Sarah stands over her corpse and smiles, telling her that "all my friends are dead".

In a mid-credits scene, Sarah receives a phone call from the original killer, who threatens to kill everybody she knows.
