304 people drowned as the car ferry sank. Four fathers recall their memories of their children; high school students who were on their field trip. Professors, lawyers, journalists, an activist, a diver, and a politician explain why the system ultimately allowed the tragedy to occur. What is stopping the next tragedy? The world has turned upside down.

The documentary Two Doors traces the Yongsan Tragedy of 2009, which took the lives of five evictees and one police SWAT unit member. Left with no choice but to climb up a steel watchtower in an appeal to the right to live, the evictees were able to come down to the ground a mere 25 hours after they had started to build the watchtower, as cold corpses. And the surviving evictees became lawbreakers. The announcement of the Public Prosecutors’ Office that the cause of the tragedy lay in the illegal and violent demonstration by the evictees, who had climbed up the watchtower with fire bombs, clashed with voices of criticism that an excessive crackdown by government power had turned a crackdown operation into a tragedy.
