Kim Do-gi is the ace driver of Rainbow Taxi, a revenge-for-hire company that helps victims get justice. However, Park Eui-cheol—Rainbow Taxi’s true owner—orchestrates a brutal conspiracy where Do-gi’s colleagues (who were like family) and his lover are viciously murdered. Do-gi is the sole survivor of the inferno, left with nothing but a burning desire for revenge against Park Eui-cheol. But Park has grown even more powerful, establishing a new company called “Rainbow T,” and instead of being able to exact revenge, Do-gi finds himself being hunted down by Park’s new fleet of killer taxi drivers. At his moment of greatest peril, Do-gi is rescued by a mysterious taxi company called “Doremi Taxi.” Following them to their headquarters, he encounters a beloved colleague—the call girl operator who used to support Rainbow Taxi’s drivers from behind the scenes. Do-gi learns that Doremi Taxi is a revenge agency founded by survivors who, like him, lost everything to Park Eui-cheol. Joining this new company of the wronged and bereaved, Kim Do-gi begins driving again.
