The SBS Friday-Saturday drama, based on the hit webtoon, follows the shadowy Rainbow Taxi crew and driver Kim Do-gi as they deliver vigilante justice for victims. Just two weeks in, the series surged to a 15.4% nationwide rating (per Nielsen Korea), ranked No. 4 among all 2025 miniseries, and topped streaming charts in Korea and overseas.
Ahead of Episode 5, producers released stills of CEO Jang (Kim Eui-sung) from a time before the Rainbow Taxi operation even existed ― a peek at the incident that may have set everything in motion.
In the images, Jang sits in a courtroom, tense and laser-focused. Moments later, he leaps to his feet as if blindsided by a ruling, unleashing raw fury before court officers escort him out. The flashback raises a burning question: What happened to Jang 15 years ago, and how did it spark the birth of his revenge-for-hire service?
Episode 5 sees the Rainbow Heroes hit the road to finally close the very first request they ever received ― the only case they failed to solve. Do-gi (Lee Je-hoon) and the team dig into the presumed murder of Park Min-ho (Lee Do-han), captain of Jingwang University’s volleyball team, who vanished 15 years ago and whose body was never found. Can the squad make the killer pay ― and unearth the ugly truth that’s been buried for a decade and a half?
Director Kang Bo-seung calls Episodes 5-8 difficult but essential ― chapters that connect directly to Taxi Driver’s origin. “In Korea, ‘I don’t remember’ is, to me, the most negatively used phrase,” he says. “People remember selectively when it benefits them, even about things that happened just yesterday. I wanted to approach this story from the perspective of someone who must remember ― someone who clings to memory as if their life depends on it. One person can say ‘I don’t remember’ to dodge trouble, while for someone else, that memory is life or death. We focus on that memory and tell the story of a man desperately holding onto it to get his son back.”
Kang also teases a special OST: an artist who read the script wrote their own lyrics and joined the soundtrack ― a fresh hook to watch for in this arc.
"Taxi Driver 3" airs Episode 5 on Friday, Dec. 4 at 9:50 p.m. KST.
