"Taxi Driver" Episode 12: Lee Yoo Joon's Brutal Death

In the latest episode of the Korean drama "Taxi Driver," Prosecutor Kang Ha Na, played by Esom, learned more about the brutal death of her colleague, Investigator Wang Min Ho (Lee Yoo Joon.)

With a mission to help save their witness, the Investigator arrived at the scene but was entangled in a fight with Goo Young Tae.

As he gets the upper hand of the situation and tries calling the police for the arrest of Young Tae, his twin brother Goo Suk Tae attacks him from behind, which causes his death.

Based on the post mortem report, the Investigator died due to multiple stab wounds, making Kang Ha Na felt guilty about the Investigator's brutal murder.

This prompted the prosecutor to arrest Goo Young Tae but was released because of the lack of evidence. "Taxi Driver" episode 12 also showed that Kang Ha Na is eager to solve Wang Min Ho's case.

However, the Seoul Northern District Prosecutors' Office, headed by Jo Jin-Woo (Yoo Seung-Mok), cited that the case will be assigned to another prosecutor.

Prosecutor Kang Ha Na Joined Force with Kim Do Ki's Team

Given that the new murder case was out of her hand, she sought Kim Do Ki's (Lee Je Hoon) help to look for justice and avenge Investigator Wang Min Ho's death.

There, the Rainbow Taxi team received a surprising request from Kang Ha Na, which the group immediately took as they planned their set up to take Goo Young Tae and Goo Suk Tae down.

The team's first mission is to look for the witness Sim Woo-Sub (Jung Kang-Hee) and infiltrate the building, which they believe is where the evil twins are hiding their captives.

Unfortunately, Kim Do Ki was surprised that the area is being used as an organ trade and was also found out that the witness was already dead.

Do Ki called Kang Ha Na and informed her about the illegal trade.

Chairman Baek Sung Mi's Plan

In the next scene, BlueBird Foundation and Taxi Driver boss Jang Sung Chul (Kim Eui Sung) learned about the illegal trade and questioned Paradise Credit Group Chairman Baek Sung Mi (Cha Ji Yeon) if she is involved with the case.

She admitted that she knew about the organ trade but was clueless that his personal assistant Goo Suk Tae and her junior managing director Goo Young Tae were also doing a side job of killing innocent people.

With this, the two created a plan to end things out and turn over the twins to the Rainbow Taxi group.

Rainbow Taxi Group Gets Deceived by Chairman Baek Sung Mi

"Taxi Driver" episode 12 showed the unification between the group and Chairman Baek Sung Mi, but Kim Do Ki was doubtful if the Paradise Credit boss can be trusted.

Despite his hunch, the group proceeds with the plan. Do Ki and Jang Sung Chul was outside of the restaurant where they set up a spy camera as Chairman Baek Sung Mi spoke with Goo Young Tae.

This was being monitored by the resident hacker Ahn Go Eun (Pyo Ye Jin) while Choi Kyung Goo (Jang Hyuk Jin) and Park Jin Eon (Bae Yoo Ram) were at the dungeon where Baek Sung Mi is hiding all their captives.

While being monitored by the trio, she offered her a drink that would make Goo Young Tae unconscious.

The goal is to get him and transfer the suspect to the prosecution; however, the plan failed, and Goo Young Tae single-handedly attacked the Paradise Credit boss.

Jang Sung Chul and Kim Do Ki barged in to help Chairman Baek Sung Mi but later found out that it was pre-recorded and it was all her plan.

Baek Sung Mi escaped alongside his men, Goo Young Tae and Goo Suk Tae.
