Wonderland

Bai Li leaves for a desert expedition, keeping constant contact with her young daughter Bai Jia. The repeated calls reveal her motherly concern even as the harsh landscape tests her focus. The tension between professional duty and family ties sets the emotional frame for her arc.

Jeong-in, a flight attendant, constant calls her boyfriend Tae-joo, an astronaut, using both real-life contact and Wonderland simulations. Their relationship is mediated by technology, blending longing with regular routines. The dual reality hints at how Wonderland mediates intimate connections.

The real Tae-joo awakens from his coma and is brought home by Jeong-in. The reunion is emotional as he re-enters life outside the hospital. This event shifts the balance of trust between them and heightens the role of Wonderland afterward.

Hae-ri, a Wonderland manager, fields video calls from her own parents who tease her about her relationship with Hyeon-soo. The domestic scene contrasts with the high-stakes issues inside Wonderland. Her job exposes how personal life and the system interweave.

Hae-ri and Hyeon-soo handle two troubling cases: a grandmother exploited by a dead grandson in the system, and Yong-sik, a dying man who may be Hyeon-soo's biological father. The stories reveal frailty in simulacra and how vulnerable people depend on it. These cases probe the moral risks of substituting real contact with digital proxies.

Bai Li's mother Hwa-ran contemplates ending the Wonderland service and telling her granddaughter that Li has died. The dilemma pits truth and closure against the comfort of simulated connections. Her decision foreshadows upheaval for both the living and the dead within the network.

As Tae-joo changes after waking, Jeong-in grows uneasy and begins turning toward the Wonderland version of him. The line between authentic affection and simulated companionship starts to blur. The shift strains their relationship and questions what it means to love someone who is no longer fully present.

Tae-joo becomes a suspect in a fire in their apartment building, complicating Jeong-in's feelings and fueling suspicion. The accusation drives a wedge between real-life trust and the comfort of Wonderland. The incident amplifies the theme of reality versus simulation.

A suspicious Tae-joo visits Jeong-in at her apartment gate and learns she subscribes to Wonderland; he emotionally bids her goodbye. The gate becomes a threshold between a fading real relationship and a social network of simulated ties. The moment underscores the consequences of living through digital surrogates.

At the airport, Hwa-ran loses track of Jia, and Wonderland service is deactivated while searching for the girl. The outage forces the family to rely on real-world action rather than virtual routes. The crisis tests how much the system can sustain without its digital support.

Within Wonderland, Bai Li attempts to leave the program to help locate her daughter, but she is blocked by roadblocks. The struggle shows how deeply the virtual world can entangle physical outcomes. Her stubborn drive pushes toward a direct confrontation with the system.

Bai Li drives through a sandstorm, pushing past obstacles and approaching the operating system, causing glitches in other simulacra. Attempts to stop her grow futile as the system teeters on collapse. Sung-joon arrives and allows Bai Li to enter the central server.

Sung-joon enables Bai Li to move from the core server to the airport network, asking Wonderland subscribers to help locate Jia. The search feels communal as families and subscribers rally to recover a missing child. The line between administrator and ally blurs as the network becomes a tool for real-world rescue.

Tae-joo arrives to rescue Jia, and she accepts the truth of Bai Li's death within the process. The rescue brings emotional resolution and redefines their family’s relationship with loss. In the epilogue, Hyeon-soo introduces his mother to the Wonderland version of Yong-sik, signaling a new harmony between memory and simulation.
