Black Museum (Black Mirror)

Whilst waiting for her car to refuel, Nish (Letitia Wright) comes across the mysterious Black Museum, an exhibit housing "authentic criminal technology". She meets the proprietor, Rolo Haynes (Douglas Hodge), who provides her with a personal tour of the place and recount the stories behind the various artifacts he collected.

In flashback, Haynes is shown to recruit subjects for medical experiments in a hospital in New York City. He persuades Dr. Peter Dawson (Daniel Lapaine) to take on a neurological implant that allows him to feel the physical sensations of others. Dawson uses this to feel the pain of his patients; over time, the repeated experience allows him to provide an accurate prognosis for a majority of illnesses.

One day, Dawson blacks out when his patient suffers cardiac arrest and flatlines during his diagnosis. This near-death experience causes Dawson to become addicted to the pain and escalate his means to feel it. Eventually, he is removed from the hospital and begins mutilating himself as a means to reach his high. When he realizes that he is also missing the "fear" that stemmed from his patients, Dawson kidnaps and kills a homeless man with a drill. The police are able to arrest Dawson, but not before he slips into a vegetative state.

In the present, Nish offers Haynes some of her water as the museum's air conditioning is broken. She spots a stuffed monkey in the exhibit, leading Haynes to recall another story.

In another flashback, Haynes convinces Jack (Aldis Hodge) to transfer the consciousness of his comatose wife, Carrie (Alexandra Roach), into his own brain so that she can live again. The operation is successful, and Carrie enjoys sharing the sensations that Jack feels in the real world. However, the shared consciousness begins to take a toll on the couple; Haynes subsequently allows Jack to control Carrie's thoughts by "pausing" her stream.

Jack subsequently meets Emily (Yasha Jackson), and the two begin seeing each other. Jealous of Carrie's influence, Emily convinces Jack to remove her conciousness entirely. Reluctant to delete it, Jack instead allows Haynes to transfers Carrie's into a stuffed monkey, which Jack subsequently gives as a gift to his son. When she wakes up, Carrie realizes that she has become a toy and is threatened by Emily to act in line or be thrown out. Eventually, Carrie - still inside the monkey - is tossed away by her son.

In the present, Haynes tells Nish that the transfer process of Carrie was illegal, which led him to be fired from the hospital. He tells Nish that Carrie is still inside the stuffed monkey in the exhibit, and unveils to her the main attraction of the muesum: a lifeless hologram projection of Clayton Lee (Babs Olusanmokun).

Sometime after his firing, Haynes coaxes Clayton - a convicted killer on death row - to sign over his rights to his post-death consciousness in exchange for a cut of the profits. After his death, Clayton is reborn as a hologram inside Haynes' museum. However, Haynes reveals to the Clayton hologram that he is a part of the electric chair simulation, and that he combined Dawson's research to allow Clayton to experience the pain of the execution. Haynes eventually opens his museum to customers and allows Clayton to be repeatedly tortured.

In the present, Haynes begins to asphyxiate as he tells his story. Nish subsequently reveals that she is Clayton's daughter: she poisoned Haynes with her water and sabotaged the AC as means of revenge. Before he dies, Nish transfers Haynes' conciousness into Clayton's hologram and leaves the electric chair on forever to torture him. Taking the stuffed monkey along, Nish makes her way back to the car as the museum is engulfed in flames.
