Zero Time Dilemma is set between the events of Nine Hours, Nine Persons, Nine Doors and Virtue's Last Reward. The game follows nine characters who have been locked up in an underground nuclear bomb shelter and are forced to play a death game called the Decision Game, which is led by a masked person known as Zero. The shelter is divided into three wards, with three people placed in each section, making up three teams: C-Team, Q-Team, and D-Team. To get to the central elevator hall and escape, the characters need six passwords; one password is revealed each time one of them dies. The characters are all wearing watches that inject them with a drug every 90 minutes, inducing memory loss. Heavily involved in the game's lore is the many-worlds theory, where every decision made creates alternate universes where the opposite was chosen; these timelines make up the game's multiple routes.

C-Team includes Carlos, a firefighter with a strong sense of justice; Akane, a member of a secret society working for a peaceful future, and who pretends to be a "neat and clean, ideal Japanese woman"; and Junpei, a childhood friend of Akane's, who has joined a detective agency to find her after she has not been heard from. Q-Team includes a naive amnesiac boy wearing a spherical helmet; Eric, an ice cream shop clerk who easily cracks under pressure; and Mira, who does not show much emotion and is in a relationship with Eric. D-Team includes Diana, a pacifist nurse who dislikes fighting; Phi, an intelligent woman who participated in the Dcom (Dwelling for Experimental Cohabitation of Mars) experiment together with Akane and Sigma to save the world from the Radical-6 virus; and Sigma, a 67-year-old man in the body of a 22-year-old. Additionally, there is a dog named Gab who is able to pass through vents between the sections to deliver messages between the teams.

The story features several loosely-interconnected narratives. Most individual narratives are linear, but the story jumps between them non-linearly.

Early parts of the story focus on two main narratives:

The first one deals with attempts to create, understand and control interdimensional portals with the form of tunnels lined with human flesh, named "flesh interfaces", created by subjecting people to large doses of LSD. Flesh interfaces are first created in 1944 in Treblinka, and research about them is abandoned around the year 2020.

The second narrative takes place in 2039, with a large share of humanity spending their entire lives connected to virtual reality Internet feeds. An unknown entity named Q hijacks the Internet to take over the minds of humanity. It's hinted that it's been empowered by the prior experimentation on flesh interfaces. The last survivor of a group dedicated to fight Q and her caretaker flee the nuclear bombing of Atlanta and, knowing that all their attempts to stop Q will be futile, start writing their life stories, trying to create another timeline in which Q is stopped.

The later parts of the story deal with two more narratives:

In one of them, a young child is abducted by a supernatural entity made of animal body parts, including horse eyes, which names itself Mother. Mother makes his parents disappear, keeps him locked at his own house and forces him to perform magic for it. His magic doesn't let him escape, but eventually he uses it to bring his future self to his rescue.

The second narrative focuses on the experience of addiction through the eyes of Nick, a failed writer struggling with alcoholism and childhood trauma. The novel Nick claims to have written reflects the first parts of the story about flesh interfaces and Q. Eventually, Nick reveals that the abducted child is himself, and the experiences with Mother triggered both his writing and his alcoholism. He doubts his own sanity, but after his roommate narrates his own experience finding a flesh interface made of bones, he is convinced of the reality of his own experiences and tries to face and understand his past. He visits the flesh interface and unknowingly uses it to travel to the past. In the final scene of the story the two versions of Nick meet, as the older one makes peace with his past and the younger one is freed from Mother.

It's hinted that Mother and Q are the same entity, and it's not clear if the rescue of Nick is part of a timeline in which Q is defeated.

There are also some small side narratives. One of them culminates with the narrator being assimilated to a flesh interface, one of them seems to document how humans got the ability to create the interfaces and one of them seems to be a metaphor for humans not being able to comprehend flesh interfaces and Q.

Q has been sighted in crime scene photographs of unsolved murders all over the world, partially hidden each time. The context of the pictures are shrouded in mystery: his appearance in them may make him the murderer, or perhaps he could be investigating it, as hinted by his stereotypical detective attire, though nothing regarding a potential role in the killings or the nature of the victims has been revealed.

In his ending, Julianna and David, along with other CIA agents, discuss Q's appearances at case sites worldwide over the last 10 days, believing him to be the common link between the cases (though they are unsure if it is the same person). While they cannot identify him, they at least manage to decipher his appearance based on the photos they have. After they set out to begin the investigation on him, a familiar silhouette can be seen on the projector screen, apparently leaving the room as well.
