Do I Look Like a Pushover?

"Dong-Gyu (Lee Chun-Hee) works as a prosecutor, but he always loses his cases. He doesn't like his job and always carries his resignation with him. One day, Dong-Gyu attends his high school reunion to meet Chang-Ho (Park Sang-Wook) who was his hero back then. Chang-Ho though does not appear. Dong-Gyu is assigned a bank robbery case. He meets the suspect in the interrogation room and is stunned to see Chang-Ho."
