The story of two young people who became swept up in the Gwangju uprising in May 1980.
Hwang Hee Tae (Lee Do Hyun) is a troublemaker who hates anything that is predictable. To break the prejudice against sons raised by single mothers, he received top grades and entered Seoul National University College of Medicine. He also plays guitar and loves going to music cafes. However, due to unexpected events, he is experiencing the harshest May of his life.
Kim Myung Hee (Go Min Xi) is a hardworking nurse who lives alone in Gwangju. Although she is not friendly enough to comfort crying patients, she is smart and skillful. Myung Hee is more like a warrior than an angel.
Lee Soo Ryung (Geum Sae Rok) is Myung Hee’s best friend, a girl from a wealthy family. She feels a responsibility to be a leader in social justice.
Lee Soo Chan (Lee Sang Yi) is Soo Ryung’s older brother. He helps his father in the family business after returning from his studies in France.
