When working as a taxi driver and living with his daughter, Jin-ah (played by Park Yoo-na), his life suddenly changes when he receives a call from an old friend, Woo-jin (played by Kim Nam-gil). Woo-jin asks for Soo-hyeok's help to protect a woman named Jin-ah (played by Lee Elijah), an investigator who is currently investigating a human trafficking case.

Although Soo-hyeok agreed to help, he was unaware that his involvement would bring him back into the criminal world. To protect Jin-ah and uncover the truth behind the human trafficking case, Soo-hyeok must utilize his skills as an assassin.
