Origins
Bruce Wayne ends up having yet another nightmare about the death of his parents at the hands of Joe Chill. Before the nightmare ends, Chill tells him "that's what happens when you try to be a hero", while citing his father's dead corpse as an example.

The Manor
After waking up, Bruce finds himself at the piano room of Wayne Manor where Alfred greets him. The latter informs him that there's a situation, and that he'll explain "downstairs." Before leaving, Alfred gives Bruce a key to open the piano, and after pressing the keys, he gets sent to the Batcave.

Suit-Up
Bruce suits up as Batman and takes his gadgets to meet up with Alfred at the Batcave

Batcave
After arriving at the Batcave, Alfred told Batman that he has awful news; he lost contact with Robin and Nightwing. Using the Batcomputer, Batman finds that only Nightwing's tracker is online and that he's not responding and heads to his location by using either the Batmobile or the Batwing.

Dead End
Arriving at the scene, Batman discovers much to his dismay that Nightwing was killed by a mysterious assailant. Reconstructing the crime scene, he learns that his killer knew exactly how he would fight. He also learns that one of Penguin's agents watched, but was chased away by the assailant, and wonders if Penguin had something to do with the murder.

Tipping Point
Using the Batwing, Batman arrives silently at the Iceberg Lounge, and finds that Penguin is about to kill one of his men for failing to defuse a bomb that destroyed half of the Iceberg Lounge. Batman manages to defeat the henchmen and interrogates Penguin, who reveals that the agent was about to reveal the identity of the killer, only to be caught and killed in the explosion of the Iceberg Lounge. It is possibly caused by the same killer. Taking Penguin's advice, Batman goes to the city morgue.

Shrapnel
Arriving at the morgue, Batman listens to reports about the explosion's victims. Analyzing the corpses with the Forensics Scanner, he finally learns that the killer's hideout is at the sewers, which is where Robin is also being kept.

Bird Cage
Batman arrives at the sewers and while walking in, he hears speakers with Joker's voice. He finds Robin stuck in a cage, but after walking in to get him out, he gets stuck too. The two work together to find anything useful to escape the cages while holding off Killer Croc in the process with electricity. Unfortunately, after Batman releases Robin, Croc uses it to his advantage and attacks and kills Robin, much to Batman's horror.

Reflections
Batman's cage suddenly turns into an elevator leading to an underground Arkham Asylum facility, where he hears screams of pain coming from the holding cells. After managing to open the door, Batman opens several cell windows with numbers 423, 424, and 425. After opening cells 423 (which contains Scarface) and 424 (which contains Victor Zsasz), he finally opens the window to cell 425 to reveal a captive Joker. As Batman attempts to leave, he finds himself locked alone inside Joker's cell which starts changing as he turns around, with letters written in blood. He then discovers much to his horror that HE was the one who murdered Nightwing, killed the agent to prevent him from telling Penguin his identity, and trapped Robin in the sewers. This all happened because Joker temporarily took control of his body, thanks to the blood transfusion he did on Batman back in Arkham City. As the horrified Dark Knight looks at the mirror and sees Joker as his reflection, the latter states that the Dynamic Duo "are together at last", making Batman realize Joker wants full control of his body, before laughing maniacally. The lights then turn off, ending the game.

Since Batman can hear numerous alarm clock noises throughout the game and hears a message on the radio earlier on the Batcave (which can be deciphered as WAKE UP BRUCE), it's heavily hinted that he is having a nightmare. These noises and messages are probably Bruce trying (and failing) to pull himself out of the nightmare.

Once Batman yet again suffers through the nightmare, he finds that Riddler has put up some puzzles around the areas in Batman's nightmare. After collecting them all and being forced again through the nightmare, Batman once again sees Joker as his reflection. Instead of taunting Batman however, Joker instead sings a mocking song about how he will permanently take over Batman's body for himself, ending with the prophetic words "Soon Bats will be gone, AND I WILL BE HERE!". The lights once again go out, causing Batman to snap out of the nightmare.

Trivia

 * There are a few continuity errors:
 * Killer Croc's appearance is a major continuity error. Here he uses his character model from Batman: Arkham Knight, despite the fact that Batman has not seen him post-Iron Heights experimentation. Croc should look the same as he did the last time he met Batman in Arkham City.
 * However, if Arkham VR does take place before Arkham Knight, then it's plausible that a year had passed and Killer Croc's torture during the Iron Heights experimentation could have been underway by then, although Croc's mutations happened out of sight from everyone who did not work at Iron Heights, including Batman.
 * Another continuity error is in the Batcave: when examining the Arkham Asylum Case File, Scarecrow's Fear Gauntlet uses its Arkham Knight design rather than the Arkham Asylum design.
 * Before saving Robin, Killer Croc can be seen in a sewer hole.
 * The events of the game could also explain Batman's reluctance to work with both Nightwing and Robin during the events of Arkham Knight, as the nightmare had shaken him to the point of keeping them away for their own safety.
 * At Arkham Asylum, after Batman arrives via the elevator, numerous screams and cries of pain can be heard. Some fans speculate this to be Jason Todd during the period when he was tortured by Joker.
 * Also, there were a couple of Easter Eggs in the story process:
 * At the beginning of Wayne Manor, you can find a few postcards by SK (Selina Kyle). Also, in the globe, you can find three newspapers about Jewelry missing.
 * At the beginning of Wayne Manor, you can go to a table that has two building figures of Lexcorp. Lexcorp's owner: Lex Luthor, the nemesis of Superman.
 * On the left of the piano, a red phone can be seen. This is a reference for the 1966' Batman television show. It play three calls in the game: Vicki Vale for Bruce not coming to a ball, Alex Drescher thanking Bruce for contribution to Arkham City, and the final one was Joker impersonating Alfred after finishing the story.
 * When you arrive to Nightwing's crime scene, if you turn around on the fire escape balcony at the beginning, you can find a copy of Alice in Wonderland and a top hat, zoom it to gain the "Through the Looking Glass" Trophy; this room most likely belongs to Jervis Tetch, and hinting that he's already planning to brainwash Batman.
 * Inside the Morgue rack, there is keycard that opens a freezer where you can find a bag of Joker's TITAN infected blood, the gun Joker used to paralyze Barbara Gordon, the crowbar used by Joker to torture Jason Todd, and Escrima Sticks belonging to Nightwing; analyzing them will unlock the trophy "Fallen Son".
 * Due to Joker's influence, his bio in the Batcave lists 45 different crimes he was convicted of, which included kidnapping, torture, extortion, racketeering, fraud, grave robbing, unlicensed dentistry, cabaret entertainment, and taxidermy, counterfeiting, bullying, cyber-bullying, badger, bear, duck, monkey, iguana, and rhino baitings, wildlife smuggling, failure to adequately restrain a rhino, identity theft, malicious mischief, trespassing, arson, assault, normal, grand, and spectacular larceny, vandalism, forgery, impersonating a police officer, a doctor and an airline pilot, livestock theft, involuntary, voluntary, and enthusiastic manslaughter, desecration of a corpse, improper disposition of a body and labeling of meat products, cannibalism, homicide, regicide, attempted omnicide, and finally, littering. When the list was done, Joker would say he regretted he didn't do more in his lifetime.
 * The convictions of impersonating a police officer, a doctor, and an airline pilot are possible references to the Steven Spielberg movie Catch Me If You Can.
 * The number 425 had appeared several times: This is the number that refers to the Joker's first appearance date in Batman #1 (April 25, 1940).
 * In Batcave, you pick up a Batphone that has a "0.425" number; also, if you tune the radio frequency to 425 (or 426~429), you can hear a group of police reporting. (acceptably, they said this number severable)
 * When you investigating three deceased Penguin thug, and go to locker entering the password, you will found that the password was "425"; also after you unlock the freezer, and use the Forensics Scanner to scan the Crowbar used by Joker to torturing Jason Todd and the Escrima Stick, the evidence number is both "425".
 * In the last act, Joe Chill's cell (which were Joker cell in the Nightmare) number was "425".
 * The Riddler once again appears in the game, and, surprisingly, breaks the fourth wall and talks to you (not Batman). Actually, he already broke the fourth wall in all of the Arkham games, but not all the time; which makes him the only one in the Arkhamverse that talks to the player.
 * If you get all collectibles, you will get an alternate ending where Joker sings Rock-a-bye Bats to signify his lust for control over Batman's body, which can also be heard in Arkham Knight. The only difference is the lyrics.
 * Arkham Knight: ¨Rock-a-bye Batsy, I'm getting free. Soon, you¨ll be the one trapped inside me. So keep breathing those great lungfuls of fear, soon Bats will be gone, and I will be HEEEERRRE.¨
 * Arkham VR: ¨Rock-a-bye Batsy, I'm getting free. Soon, you¨ll be trapped inside me. No need to be scared, you've nothing to fear, soon Bats will be gone, and I will be HERE.¨
