Exit (2020) Timeline Explained – Every Event in Order

Yong-nam lies about having a successful career because he wants to impress Eui-joo, whom he has feelings for. Since he's currently unemployed and living with his parents, he fabricates a story about a better life to make himself seem worthy of her. This lie stems from his insecurity about his current situation and his desire to present himself favorably to someone from his past.

Foreshadowing: Earlier, his sister Jung-hyun pressures him to clean up his act for their mother's birthday, hinting at his pattern of avoiding responsibility.

The rooftop door is locked, which is common in many buildings for security and safety reasons. This forces Yong-nam to improvise by smashing a window and using his climbing skills to reach the adjacent building, opening the door for his family from the other side.

The rescue helicopter has a strict weight limit, and there isn't enough capacity to take both Yong-nam and Eui-joo along with his family. This forces them to stay behind while his parents and sister are evacuated, creating a critical moment where they must find another way to survive.

When Yong-nam and Eui-joo spot trapped students in another building, they choose to signal the helicopter toward the students instead of themselves. This selfless act demonstrates Yong-nam's character development from a self-absorbed liar to someone willing to sacrifice his own survival for others.

The toxic gas continues to spread and rise, making ground-level escape impossible. The tower crane represents the highest point in the area, which Yong-nam believes will put them above the gas cloud. Since conventional routes are blocked and the gas is advancing, reaching the crane becomes their only viable survival option.

Foreshadowing: Earlier, they wrap themselves in improvised safety gear to head to higher ground, establishing that altitude is their only advantage.

The drones appear to be part of the emergency response system or surveillance network deployed during the disaster. They provide directional guidance toward the tower crane, likely because the operators recognize the two survivors are attempting to reach safety at the highest point. The drones assist by leading them through the chaotic environment and even helping create a rope bridge.

Foreshadowing: When the gas station explodes, the situation becomes even more urgent, prompting more drones to converge on their location.

The drones are not designed to support human weight. When Yong-nam uses one drone to suspend a rope between buildings, the combined weight of both Yong-nam and Eui-joo proves too much for the drone's capability. The drone loses power and they fall, though they miraculously survive the impact.

Jung-hyun stumbles during the evacuation to the roof and falls behind, exposing her to the toxic white gas for longer than the others. The gas spreads rapidly and is extremely dangerous, so even a brief exposure is enough to incapacitate her. This forces the family to leave her behind temporarily, creating emotional tension.

Rain begins to fall as Yong-nam and Eui-joo are reunited with his family after their rescue. The rain gradually washes away the toxic white gas from the city, symbolizing the end of the disaster and the beginning of renewal. This natural phenomenon provides a hopeful, cleansing conclusion to the crisis.

Foreshadowing: The entire film takes place under clear conditions, making the sudden rain a deliberate narrative choice for the ending.

Yong-nam was once one of the best rock climbers in college, and those skills prove crucial during the disaster. When the rooftop door is locked, he smashes a window and uses a makeshift harness to scale to the adjacent building. His agility and experience with heights allow him to navigate the dangerous urban terrain throughout their escape, ultimately leading them to the tower crane.

Foreshadowing: His sister pressures him to 'clean up his act,' suggesting his past achievements contrast with his current stagnation.

The gas station near the terrorist truck explodes, likely triggered by the fire from the initial attack or electrical malfunction in the chaos. This explosion sends a new wave of toxic gas rushing toward Yong-nam and Eui-joo, forcing them to flee their building before they can be rescued and pushing them toward the tower crane as their only remaining option.
