The tvN Saturday/Sunday TV series "Audit" (written by Choi Min-ho/directed by Kwon Young-il) will be broadcast today (20th)
In episode 5, Shin Ha Kyun begins a new investigation into a terrorist who is making brazen threats to poison the food of construction workers.
Previously, as soon as he was appointed as the head of the audit team at JU Construction, he solved various incidents and accidents, from the tower crane collapse accident to the housing construction project EMBEZZLEMENT.
However, as the audit team's success increases, the number of people who are jealous of them also increases, and Chail even receives a threatening letter, so every day is filled with a sense of crisis.
In particular, the threatening letter that Chail received read, "If you do not investigate the corruption at the construction site cafeteria, we will launch a terrorist attack on the cafeteria." One by one, the workers at the construction site complained of stomach pains,
It seemed like the beginning of a new case. Who sent the threatening letter and what was the purpose of that person are all in the spotlight. The photo released in this situation shows the name of the audit team that has begun investigating the threatening letter.
The scene includes a shot of the letter's contents being examined meticulously, as if to try to understand the perpetrator's intentions, and the shining gaze of the letter creates a sense of tension.
The team leader, Chail, and the audit team members, Goo Han-soo (Lee Jung-ha), Yoon So-jin (Jo A-ram), and Yoon So-soo (Yoo-soo),
Mu Kyung-seok (Hong In), Ok Ah-jung (Lee Ji-hyeon), and Moon Sang-ho (Oh Hee-jun) are also attending the meeting with serious expressions on their faces, suggesting that the investigation into this case will not be easy.
Attention is focused on whether the audit team will be able to catch the culprit of the blackmail letter and solve the fraud at the restaurant. Meanwhile, the JU Construction audit team's lone struggle to catch the terrorist is unfolding.
Episode 5 of the tvN Saturday-Sunday TV series "Audit" will be broadcast today (20th) at 9:20 pm.
