V/H/S: Viral

In this wrap-around story, amateur videographer Kevin constantly films his girlfriend Iris, while living with an abusive grandmother who bloodies his nose off-screen. Seeking viral footage, Kevin attempts to record a televised high-speed police chase near his neighborhood but misses the truck as it speeds past. Soon after, Iris receives a mysterious video call and wanders outside in a daze, where she is abducted by the truck's driver. Kevin pursues the vehicle, guided by disturbing images of Iris sent to his phone, while the truck circles the area broadcasting signals that turn local residents violently insane. Upon catching up to the truck, Kevin finds scattered body parts, a driver's seat containing only disembodied hands duct-taped to the wheel, and a stack of televisions in the back. Iris appears on a screen demanding he upload the broadcast footage to the internet; when he refuses, she begins to brutally mutilate herself, forcing Kevin to comply. Exiting the truck, he discovers Iris's actual corpse slumped against the vehicle with her phone wedged in her mouth, realizing she had been dead for some time and he was manipulated into uploading the signal. When Kevin removes the phone and looks at his own bleeding nose on the screen, it is implied that he has also been affected by the transmission. The final shot reveals the Los Angeles skyline descending into chaos with smoke and flickering lights, confirming the uploaded video has gone viral and is affecting thousands.

Dante the Great, an untalented illusionist, discovers the infamous cloak of Houdini that grants him the power to perform real magic. He quickly becomes famous, though he learns that the cloak requires regular sacrifices to work. Dante hires a series of female assistants and videotapes their violent deaths at the hands of the cloak. When Scarlet, his latest assistant, discovers Dante's stash of tapes, she alerts the police. Dante uses his magic powers to escape captivity and kill an entire SWAT team. Scarlet then confronts him, and the two duel over the magic cloak. Though Scarlet is briefly able to take it from him, he overpowers her and recovers it. Before Dante can kill her, Scarlet uses a trick he taught her to immobilize him, and the cloak feeds on him instead. Scarlet burns the cloak, only to find it in her house; the segment ends as arms reach from inside the cloak and grab her, having selected her as the cloak’s new host.

Parallel inventors named Alfonso cautiously meet through an interdimensional portal and explore each other's seemingly mirrored worlds, which actually possess divergent dominant religions. In the alternate universe, Alfonso is disturbed by a pornographic snuff film and a bizarre ceremony prompted by his wife, Marta. Fleeing outside, he spots a blimp with an inverted cross and is captured by two Orioles who reveal demonic features, including a demonic penis. After stabbing one and escaping to his alternate home, Marta reveals her own demonic vagina, prompting him to punch her and flee back to his home dimension. There, the demonic Alfonso has already assaulted the normal Marta in her sleep and stabbed the normal Alfonso before returning to his own universe. Ultimately, both versions of Marta kill their respective husbands, blaming them for the horrific actions of their alternate-dimension doubles.

A trio of skateboarders perform various stunts as the videographer they hired pushes them into increasingly dangerous circumstances in the hopes of filming a snuff film. After they become bored, the videographer suggests they continue the film shoot in Tijuana, where they subsequently become lost after buying fireworks. Once they find a suitable place, a flood channel, the videographer encourages them to again perform more stunts. When one of the skateboarders injures himself and bleeds on a large pentagram drawn on the ground, his blood quickly boils despite the apparent normal temperature of the pavement on which the pentagram is drawn. Almost immediately, a group of cloaked cultists attack them. Using pistols and improvised weapons, including their skateboards, the skateboarders kill the cultists, though one of the trio was killed in the fight. The dead cultists then rise as reanimated corpses, and mount a second attack. During the second attack, the skateboarders use the fireworks they bought earlier to destroy several of the skeletons. The surviving skateboarders then flee back toward the border as a monstrous creature appears and presumably eats the videographer along with his camera.
