Taxi Driver 3 ending explained: What is the truth behind Yoo Seon-a’s death?

In the penultimate episode of the Korean drama, viewers see Kim Do-gi re-enlisting in the military under the pretext of assisting with an emergency golden eagle nest survey, a cover arranged through senior officials. He also brings in the Rainbow Taxi team to operate alongside him. While this assignment appears routine on paper, Do-gi’s true motive is far more personal. He returns to the military to investigate the suspicious death of Seon-a, his former subordinate and comrade, whose name has been posthumously disgraced as a traitor.
The finale of Taxi Driver 3 then rewinds to a flashback set seven years earlier, revealing what really happened to Seon-a. During her service as a master sergeant, Yoo Seon-a was assigned to a border operation overseen by Colonel Kim Tae-hyun. On the night before the mission, she saw two officers secretly leaving the base and followed them, noticing suspicious behaviour. What she uncovered was a carefully planned false-flag operation.
Seon-a discovered that explosives were being planted inside the vests of the soldiers in her unit. The plan was to kill the entire unit during the operation near the B24 border zone and blame the resulting explosion on North Korea, thereby manufacturing a military crisis. Realising that her fellow soldiers were being treated as expendable pawns, Seon-a decided to save them. The next day, she sent her unit back under the guise of operational changes, wore a vest planted with explosives and attempted to deliver the evidence to headquarters.
However, knowing that the explosion might occur at any moment and that she might not survive, Seon-a followed the survival instructions Do-gi had once taught her. She quickly hid her body cam in a bird’s nest to ensure the truth would be discovered later. A few moments later, the explosion occurred, and Seon-a sacrificed herself trying to save her comrades, all the while becoming a victim of the very conspiracy she attempted to expose.
Is Kim Do-gi able to avenge Yoo Seon-a?
Yes, he is.
After uncovering Seon-a’s hidden body cam footage in the present timeline, Do-gi realises that the operation which killed her was not an isolated incident. Do-gi also discovers that the same network of senior military officials responsible for her death seven years earlier is preparing to carry out another staged incident, once again targeting frontline soldiers and planning to blame North Korea to provoke military escalation.
The mastermind of the operation is ex-lieutenant general Oh Won-sang, who, despite being dishonourably discharged for sexual misconduct, continues to orchestrate the plan from outside the military through active-duty allies. Won-sang’s ultimate objective is to trigger nationwide martial law in South Korea, allowing the military to seize extraordinary powers under the guise of a national security crisis.
To stop the deadly operation, Do-gi and his Rainbow Taxi team hatch an elaborate plan. As the staged incident moves forward, multiple groups of soldiers are ordered to be positioned near the border by Colonel Kim Tae-hyun, one of Won-sang’s allies. However, Won-sang’s plan to detonate their vests collapses at the final moment. It is then revealed that Do-gi and the team secretly swapped the explosives for fireworks. When Oh Won-sang attempts to trigger the explosion, fireworks erupt across the sky instead.
Meanwhile, Do-gi deliberately turns the site into a public event. He invites reporters, civilians and students, and even brings in the K-pop group Elements to stage a guerrilla concert. Fans arrive with light sticks, cameras start rolling, and the incident unfolds in full public view, leaving no room for the conspirators to control the narrative.
With the operation exposed, Seon-a’s name cleared, and evidence already secured, the police move in and arrest all the generals and active-duty officers involved in the mission. However, Oh Won-sang manages to flee the scene.

In the closing moments of the show, the Rainbow Taxi team pursues Won-sang, but the chase turns violent when Won-sang’s car crashes into the van carrying An Go-eun, chief Choi Gyeong-gu and Park Jin-eon. Do-gi and Jang Seong-cheol arrive soon after and pull the trio to safety, thus saving them.
Soon, the disgraced former general, injured and cornered, opens fire on the group. In the ensuing exchange, Go-eun is hit. Eventually, Do-gi steps forward to confront Won-sang directly, condemning his actions and warning that his ideological obsession would have cost countless innocent lives. Won-sang dismisses him without hesitation, insisting that such sacrifices are justified for what he considers the greater good, and keeps firing.
As Do-gi closes in to disarm him, he is shot once in the chest and then again in the stomach. Despite his injuries, Do-gi refuses to fall back. Declaring that he will never submit to someone like Won-sang, he surges forward, pins him down, and, in the struggle, the gun discharges again. Locked together, the two tumble off the cliff into the river below. The Rainbow Taxi team rushes to the edge in horror, watching the water beneath them turn red, with no immediate sign that either has survived.
The crime series briefly leaves Do-gi’s fate ambiguous, echoing the earlier sacrifice of Seon-a. However, the final scene provides clarity. Back at the Rainbow Taxi base, the team is shown preparing their next case, and Do-gi is there with them, alive and back in action.
