Keenly working at the point where his artistic identity and persistent attention on modern Korean history meet, director Lim in this film focused on where the history of oppression and struggle intersect between Gwangju and Buenos Aires. In both cities, a great number of people who fought against the dictatorship were slaughtered and disappeared. The people of both societies still live with that trauma. When the testimonies of the victims of the two cities cross over, the film gives us chills as the eerie history of the two is very similar. Through "Good Light, Good Air", director Lim asks us how we will remember the past from where we stand right now.
