Season Four, people, in three minutes.

Let's begin.

When John Daly uploads his office crush's DNA

into his interactive space world,

she tries to hack his system

and notifies her real-world self

but Daly finds out and gets angry.

Cole comes up with a plan to get

Daly's control device but Walton is hesitant.

Cole seduces Daly and blackmails herself

with her own nudes.

Real-world Cole steals back the DNA

of the crew members and virtual Daly is abandoned,

now chasing his others through asteroids.

Walton sacrifices himself to repair the ship.

The crew is freed and Daly is forever trapped.

Marie implants her child, Sara, with a monitoring system.

Sara grows up an outcast due to her

parental advisory settings

and her mother deactivates it.

Fast-forward and Sara is normal

but goes out partying and Marie can't find her.

Marie begins to monitor her again

and finds out about her coke dealer boyfriend, Trick.

She threatens him and slips Sara a birth control pill.

Sara finds she was monitored this whole time

and beats her pixelated face in and runs away.

Rob and Mia kill a cyclist on the road.

They ditch his body and years later,

Rob tracks her down,

saying he's going to come clean about the crime.

Mia kills him while at the same time,

a pizza truck hits a pedestrian outside of her window.

When the pedestrian files his insurance claim,

investigators access memories of witnesses

and Mia is questioned.

When Shazia, the investigator, sees the murder

from Mia's memory, Mia kills her

and drives all the way to Shazia's home

and kills her family.

Police reveal upon investigating that the baby was blind.

Frank and Amy are set up on a date

by a matchmaking system

that only allows them 12 hours together.

They spend the night and go their separate ways.

Both critical of the AI's matchmaking,

they quickly assign their next dates

which lead to long, painful relationships

and short, shallow ones.

The two are eventually paired up again

and agree not to check their expiration date

but Frank does and they break up.

Amy's ultimate match is calculated

and as a last farewell, the two meet for dinner,

and climb the walls and find

it was all a simulated dating app.

Bella and her friends attempt to retrieve

a mysterious box to help their sick friend Jack

but are attacked by a mechanical guard dog.

It chases after Bella but she manages

to drain its battery while stuck in a tree.

Bella breaks into a house to steal supplies

but the dog catches up and though she blinds it

with paint, the dog's shrapnel shoots her

with a tracking device.

She destroys the dog but when she notices

she's been tagged, she sends a goodbye

to her loved ones and kills herself.

The mysterious box contained teddy bears.

Nish visits a museum where owner Rolo Haynes

explains in his past how he pioneered

a neurological implant for Dr. Peter Dawson

to feel what his patients felt.

Dawson experiences death and becomes addicted

to pain and killing others,

eventually becoming comatose.

Moving on, Rolo explains the story

of a stuffed monkey that came from a man

named Jack whose wife Carrie was in a coma.

Rolo implants Carrie into Jack's brain

and eventually the monkey.

Rollo shows Nish a conscious hologram

of a controversially convicted killer.

He explains how he swindled the rights

of the prisoner and allows museum-goers

to activate the electric chair.

Nish reveals that she is prisoner's daughter

and has poisoned Rolo, swaps his subconscious

with her father's, and with the help

of her mother's conscious, frees her father

while leaving Rolo in eternal agony.

And that is the story of Black Mirror, Season Four.
