Joo O-min is a city desk reporter. She is interested in a series of suicides at Mapo Bridge and wants to cover the issue. But her boss tells her that 'everyday suicides' do not have what he calls news value. Discouraged, she visits Mapo Bridge while writing a story of a teenage girl's suicide and meets Ma, the homeless who lives on the bridge and chats daily with the crisis call center consultant. She approaches him after finding out that he has witnessed countless suicides at the bridge in the past year. But Ma shies away from her, thinking that journalists are only superficially interested in suicides, only after someone has died. One day, Ma hears that the crisis call center consultant whom he talked to on a daily basis was suddenly fired. He threatens the crisis call center that he will jump to death if they do not rehire her. This incident reminds Ma of the first time he visited Mapo Bridge to commit suicide and the overwhelming sense of loss he felt at that time. He kneels down in front of Joo and wails. Ma seems to calm down after befriending Joo and meeting a new call center consultant. But he doesn't know that the layoff was a scheme concocted by the call center consultant who found his daily calls annoying.
