In the third season of Taxi Driver, Kim Do-Ki and his Rainbow company team embark on a series of revenge cases that shed light on pressing LGBTQA+ issues, slut-shaming, and the double standards surrounding sex positivity. They confront the challenges faced by both men and women, especially sex workers. Meanwhile, they also tackle a tourist scam targeting single South Korean men, as well as a chilling group of serial killers haunting the city on Halloween.
Amidst the chaos, Kang Hana unexpectedly reenters their lives, bringing her own share of secrets and mysteries. Furthermore, Do-Ki encounters a young woman named Noa, accompanied by her daughter Sae-Byeok. Noa claims to be Do-Ki's long-lost half-sister, revealing a hidden family connection that her missing father concealed for years. Inspired by her newfound bond, Noa joins the Rainbow group, introducing her group of sex workers called "The Coven." She envisions establishing a nightclub and fashion boutique near the cab company, offering her friends a fresh start with the support of the team.
As the season progresses, tensions rise, leading to a near-fatal attack on Do-Ki. The incident forces the team to adapt and adjust without their leader, as he undergoes a challenging period of recovery. Will they be able to overcome this obstacle and continue their pursuit of justice? The season culminates in a gripping climax that tests their resilience and determination, leaving audiences on the edge of their seats.
