Shake, Rattle & Roll Extreme (2023) Plot Summary

Lyka lives with her single mother Ingrid, her older half-brother Patrick, their housekeeper Hasmine, and their pet dog Choppy. One day, after her tablet breaks and she is blamed by Hasmine and Patrick for several mishaps around the house, while also feeling neglected by her mother, Lyka breaks down in her room. Her phone inexplicably begins playing a children’s show featuring a mascot named Gary the Goat, which appears to possess Lyka, who then repeats an incantation from the show that invites Gary’s spirit into their home. A stuffed goat toy suddenly materializes in her room, which Lyka tells Ingrid and Hasmine was a gift from a “friend”. Choppy, sensing the spirit’s presence and persistently barking at the toy, is violently killed one night.

As Lyka becomes engrossed in Gary’s show, paranormal events begin to occur in the house. Patrick’s phone inexplicably turns on and captures an intimate moment between him and his girlfriend Margot. When the photos later surface on Lyka’s tablet, Ingrid confronts Patrick, leading to a heated argument that causes him to run away. Meanwhile, Hasmine becomes terrified after witnessing Gary’s demonic, goat-like form watching over Lyka as she plays with her tablet.

The following day, while Ingrid goes to find Patrick, Hasmine is attacked and decapitated by Gary. Margot visits the house only to find a horrified Lyka, and is killed as well. Ingrid and Patrick return, discover the corpses, and find Lyka being terrorized by Gary. In the ensuing attack, they discover that Gary is repelled by a crozier belonging to the house’s blessed religious statue of Jesus, Mary, and Joseph. Ingrid uses the staff to drive Gary back, allowing her children to escape, but is severely injured and eventually overpowered in the backyard. As Gary begins to strangle Patrick, Lyka climbs a statue of Saint Michael and dislodges its sword, which she throws to Ingrid. Ingrid uses the sword to stab and destroy Gary, before collapsing from her injuries as Lyka and Patrick gather by her side.

A group of social media influencers, including Vee, Adelle, Ashley, and Chef Kino, travel to a remote luxurious mansion to collaborate with fellow influencers Robin and Raye for a mukbang live stream. They are later joined by Vee’s boyfriend, Lionel, whose relationship with her is strained. For the night, Chef Kino cooks the meat supplied by the eccentric Mang Isko, unaware that it is the remains of Adelle’s assistant Beyonce and Ashley’s assistant Hannah; both had been lured away and killed by unknown creatures, who then assumed their forms.

During a party, the group notices strange behavior from “Beyonce” and “Hannah”, including cryptic comments suggesting the group unknowingly consumed their friends’ remains. The impostors eventually reveal themselves as century-old shapeshifters undergoing a ritual called “transfiguration”. After the party disperses, Raye, Robin and Mang Isko, also revealed to be shapeshifters, coordinate an attack on the guests. Adelle survives an initial attack and alerts the others. She and Ashley hide together while live-streaming the chaos, but Ashley ultimately pushes Adelle as bait. She is later cornered by Mang Isko, who thanks her for luring the group before she is killed and eaten by the now-transfigured Adelle and other monsters.

Vee and Lionel fend off the monsters while simultaneously bickering about their relationship, eventually culminating in Lionel staying behind to allow Vee to escape. Once outside, Vee meets Lionel and believes he has survived until quickly realizing he has also been transfigured. Before she can escape, Raye, Robin, and Mang Isko kill her.

The next day, Chef Kino, spared due to the monsters taking a liking to his cooking, is forced to prepare dishes using the influencers’ remains. The transfigured influencers resume the mukbang, which goes viral online, prompting Robin and Raye to begin planning their next collaboration for new victims.

Trina, her boyfriend Moze, and their friends Alfie, Bong, and Shai encounter their friend Coy while passing through his village during a road trip. Coy invites the group to spend the night near a nearby river to watch a meteor shower. While crossing the river, Bong discovers fragments of a meteorite and becomes infected by a parasite that emerges from the rock upon contact. When Shai tries to help him, Bong becomes violent and stabs her before being killed by the rest of the group. The friends place Bong and Shai’s bodies in a nearby hut, and Moze and Alfie set out to find help, narrowly surviving an attack by two similarly infected villagers.

Back at the hut, Trina is attacked by the reanimated Bong and Shai but is rescued by Coy, who reveals that his village has been overrun by zombified residents infected by parasitic organisms from the meteorites. The group finds refuge with the village captain at her house, along with a pregnant woman named Faya. While looking for a restroom, Trina discovers several corpses and is captured by the captain, who had drugged the others’ drinks. At gunpoint, the captain forces Trina into the basement to reveal her zombified son, whom she has been keeping alive by sacrificing uninfected villagers. Trina manages to escape by pushing the captain into her son, who kills her.

Trina wakes her friends and flees with them and Faya. When their tricycle breaks down at a nearby school, the noise of Moze’s attempts to restart it attracts a horde of the infected. Coy is caught and killed in the chaos. They eventually reach a warehouse, where Moze and Alfie are attacked by infected workers. Alfie becomes infected in the skirmish, forcing Moze to kill him. Meanwhile, Faya goes into labor and is helped by Trina. The noise draws more of the infected, prompting Moze to give Trina the keys to a truck while he distracts the horde, allowing Trina, Faya, and the newborn to escape.

On the road, Faya succumbs to childbirth complications and dies, leaving Trina to continue alone with the baby. She calls her mother to tell her she is on her way home, as a news broadcast reveals that the meteor shower triggered a global outbreak of the “rage-borne disease”.
