The play profiles a serial killer from his family, background, society and universe to reexamine his role in ethics; that is, how is “the self” constructed? And how is violence bred in the self-construction process? The play has only two actors; one of them plays the serial killer, the other plays all other characters around the killer including mother, police, helper, universe captain, etc. Two projectors and eight television sets are installed on the floor to manipulate the image-created spaces and the temporal and spatial sense in real time theatre performance. For each of the various relationships between the characters on stage, the video creates different virtual time-spaces and sceneries, constructing a glamorous but brutal masquerade carnival in which the reality of “self” seems questionable.
