Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

EP 01

The Ghost and the Grid

February 16, 2022

In 2005, a solar catastrophe destroys a satellite and establishes just how much humanity depends on the Grid. Fast-forward to 2021: Detective Jung Sae-byeok is mid-arrest when she witnesses something impossible — a mysterious woman appears from nowhere and pulls a convicted murderer out of harm’s way. The show moves fast and commits early, refusing to ease you into its strangeness. By the final minutes, you’re in.

EP 02

Impossible Results

February 23, 2022

Sae-byeok files her official report on the woman — and almost immediately the Grid Bureau swoops in to assert control. A DNA analysis comes back with results that should be physically impossible. Sae-ha is assigned to the case from the Bureau side, and the two begin a wary, parallel pursuit that makes clear early on: they want the same woman for very different reasons.

EP 03

1997

March 2, 2022

The year the Grid was born starts revealing its secrets. Sae-ha and Sae-byeok independently uncover evidence linking the Ghost’s appearances across decades to a deliberate, calculated timeline — not random acts of intervention. The suspicion that the Ghost is not a criminal but a guardian begins to take shape, and the show tightens its mystery considerably around the edges of what the Grid actually cost to build.

EP 04

Stand Down

March 9, 2022

Sae-byeok is transferred — a quiet administrative punishment for refusing to hand over her investigation. She doesn’t stop. Her stubborn refusal to accept the Bureau’s version of events is the most compelling character beat the drama has offered so far, and Kim Ah-joong plays the obstinacy without making it feel self-righteous. The Bureau’s willingness to sideline a police detective rather than simply answer her questions says everything about what they’re hiding.

EP 05

The Trap

March 16, 2022

The Bureau goes public — an all-points bulletin on the Ghost and Ma-nok, paired with deliberately false information about Grid damage designed to flush the Ghost out. A reward is announced. Sae-byeok races to reach Ma-nok at a train station before the Bureau closes in first, and the episode delivers its best action sequence yet — chaotic, tight, and high-stakes in ways that feel earned rather than manufactured.

EP 06

Aftermath

March 23, 2022

Ma-nok is captured, then immediately pulled from Sae-byeok’s custody by Deputy Director Choi Sun-wool, who recruits Sae-byeok to formally join the Bureau’s side. The Ghost makes a dramatic appearance at Bureau headquarters — and live rounds are fired. Sun-wool is killed in the chaos. What follows is the episode’s real gut punch: Sae-ha receives footage of the Ghost injecting something into his mother, and new testimony places Wi-han at the scene of his father’s death years earlier.

EP 07

Every Loop

March 30, 2022

The drama’s best episode. Sae-ha implants the Ghost’s teleportation chip into his own arm and begins traveling through time to prevent his father’s death — and discovers that no matter what he does, his father dies. Sometimes at the Ghost’s hands. Sometimes at his own. In one timeline he finds Sae-byeok horribly scarred and voiceless. The show forces its lead character — and its audience — into a genuinely devastating reckoning with fate versus consequence. The episode ends with Sae-ha accidentally causing the very death he was trying to prevent.

EP 08

Reset

April 6, 2022

Sae-ha returns the chip to the Ghost and steps back from time travel. The Bureau storms the facility. Eo-jin is killed in the explosion — until the Ghost reverses time by several days, restoring both Eo-jin and Sun-wool to life and extending Sae-ha’s mother’s health. The price of this reset: Ma-nok escapes, and immediately kills the subway station cleaner who had been sheltering him. The show refuses to let any victory land without a cost.

EP 09

Blood

April 13, 2022

Cross-referencing DNA yields the drama’s most uncomfortable revelation: Sae-byeok is genetically related to both Ma-nok and the Ghost. The woman she has been hunting and the murderer she arrested share her blood. Sae-ha turns himself in to Sun-wool. Ma-nok’s suppressed childhood memories are restored in Bureau custody. When Sae-byeok learns what the DNA means, she goes after Ma-nok herself — and Eo-jin has to physically stop her.

EP 10

Infinite

April 20, 2022

The Bureau uses Sae-ha as bait — electromagnetic radiation embedded in his skin as a tracking signal. Ma-nok escapes, and a masked rival time traveler removes his GPS tracker. Then Ma-nok finds Sae-ha on the street, remembers what was done to his father, and drives a crowbar into his stomach. Sae-ha bleeds out in Sae-byeok’s arms — and the Grid solidifies the moment he dies. A year later: Sae-byeok in the countryside with her infant daughter, Eo-jin arriving with altered appearance and impossible knowledge, the Bureau’s buildings consumed by blue light, and a very much alive Sae-ha waiting in a safehouse with the Ghost. The series ends without closing a single door.

Full spoilers ahead — everything that happens in the finale and what it all means.

The Bait and the Trap. The Bureau’s endgame in episode 10 is cold and precise: use Sae-ha as a human signal tower, his skin irradiated enough to track the Ghost when she inevitably appears near him. Ma-nok is allowed to escape as a secondary lure. But a masked man — a rival time traveler the show has kept deliberately obscured — dismantles the GPS tracker before the Bureau can complete the net. Then Ma-nok finds Sae-ha not as part of anyone’s plan, but out of raw, personal hatred. He has recovered his memories. He knows Sae-ha killed his father, even if it happened in a timeline that no longer technically exists. A crowbar. The street. Sae-byeok holding him as he goes.

Death That Saves the World. Sae-ha’s death is not wasted in a conventional sense — it is, the show implies, exactly what was always going to happen. The moment his life ends, the fading Grid stabilises and solidifies across all layers of time simultaneously. His death completes the circuit that the Ghost could never close by any other means. It answers the question the series has been asking since episode one: why would the Ghost save a murderer? Because the chain of events that led to Sae-ha’s death, beginning with Ma-nok staying alive long enough to pull that crowbar, was the only path to a stable Grid. She wasn’t protecting a criminal. She was protecting the conditions required for a single, specific moment.

The Ghost and Sae-byeok — What Passes Between Them. In the aftermath, the Ghost and the masked rival time traveler engage in a battle near the Bureau’s buildings. The Ghost freezes the moment and connects with Sae-byeok in a shared force field — not words, but something closer to recognition. Two women who share blood, who have been on opposite sides of the same event, who both know now what was at stake. The Ghost withdraws. Sae-byeok doesn’t stop her. The series never explains what the Ghost communicated. It doesn’t need to.

One Year Later — and Eo-jin’s Return. Sae-byeok has relocated to the countryside with her infant daughter, Byul — the child she saw in a vision earlier in the series, the vision she didn’t understand at the time. Eo-jin arrives urgently. He looks altered. He knows Byul’s name without being told. He has clearly traveled from a different timeline, carrying information that hasn’t happened yet for Sae-byeok. He tells her she needs to leave immediately. She goes. The Grid’s buildings erupt in blue light behind them. The masked man reports to a superior — revealed in cameo as a figure of considerable, unidentified power — that the Grid has been wiped from all of time.

The Safehouse — and the Infinite Loop. The final shot: Sae-ha, alive, waiting in a safehouse. The Ghost enters, and she gently takes Byul from someone’s arms. The four of them — Sae-ha, the Ghost, Sae-byeok, and the daughter who apparently survived whatever just happened — are together in a room while the world outside burns blue. The show offers no resolution because resolution would betray the premise. The battle across timelines is ongoing, infinite, and recursive. Someone will always be traveling backward, making choices, paying costs. The Grid was never just a shield. It was the first move in a game with no final turn. Grid doesn’t end. It simply stops letting you watch.
