Deadstream (2022)

Disgraced internet personality Shawn plans to livestream himself spending the night in Death Manor, a purportedly haunted house where several people have died. After he arrives, Shawn throws his spark plugs in the woods and locks himself inside with a padlock, and tosses the key down a grate.

Shawn recounts Death Manor's reported haunting by the ghost of Mildred Pratt, a wealthy Mormon heiress and failed poet who died by suicide after her publisher and paramour Lars's sudden death. Subsequent occupants of the house died mysteriously and the place was eventually abandoned. While exploring the house, Shawn discovers and destroys a symbol hanging in a closet.

While Shawn attempts to provoke the spirits via a séance, he fearfully shuts himself in his room after hearing strange noises. It is revealed to be Chrissy, a massive fan who has traveled to Death Manor to meet him. The two find Mildred's poetry book and try to speak to her spirit through a spirit board. Chrissy convinces Shawn to recite a Latin phrase to put the ghosts to rest.

Disturbed and annoyed by her behavior, Shawn demands that Chrissy leave. Instead, she suddenly bites his neck and Shawn stabs her in defense. Believing he's killed her, Shawn momentarily leaves but finds her body gone. Shawn searches the grate where he had thrown his keys, but only finds the key to a box containing a severed finger and a picture revealing that Chrissy is actually Mildred Pratt. Viewers inform Shawn that the symbol he destroyed earlier was a hamsa meant to protect against evil and that the Latin phrase he recited was used by Mildred to bind souls to herself. An elderly viewer tells Shawn that the ritual requires a sacrifice of flesh. After being terrorized by ghosts, Shawn jumps out the second-floor window.

Shawn finds the spark plugs and damages his tablet fighting a ghoul off. Cut off from his viewers and resigned to his fate, Shawn takes shelter in his car and reads from Mildred's book of poetry. He discovers the incantation that Mildred used to gain her satanic powers is in one of her poems. Shawn realizes Mildred never wanted a family, but an audience for her poetry. Shawn's audience inspires him to complete the ritual and banish her spirit.

Shawn returns to the house to challenge Mildred. Shawn makes it back to his equipment to retrieve a spare tablet and reads the comments that translate the incantation. While setting up the ritual, Shawn apologizes for all of his insensitive stunts, racism, and poor first apology, vowing to be better.

After a grueling fight with Mildred, Shawn reads the incantation, which fails. Spotting her severed finger, he remembers the ritual requires a sacrifice and cuts off a finger to complete the ritual. The ritual causes Mildred to be dragged into a blood-filled basement by an unseen force. Shawn celebrates, thanking his now-massive viewer count for helping him survive the night. However, as he is about to exit, he is surrounded by Mildred's own audience and his livestream cuts off and ends.
