On 16 April 2014, the Sewol Ferry capsized in the southern region of South Korea: 304 passengers died, including 250 high school students. Despite an international outcry, there has not yet been a comprehensive investigation into what caused the Sewol to sink and why the passengers were not rescued promptly. This article discusses how performance can represent something that defies explanation because we do not know how or why it happened. Yellow Ribbon’s Talent Show, Namsan Arts Centre’s From Pluto, and Camino de Ansan performed the role of the students who died. Taking these three case studies, this article analyzes the ways in which they strive to represent the unrepresentable as they attempt to document the sinking and achieve justice, while memorializing the victims and arguing for the necessity of a more safety-conscious society.
