On a hot summer day, a performer swims from the town centre to the river on a tricycle. The choreographer-director attempts to intervene in the everyday lives of local residents via an improvisation, to investigate the traces of the audience’s reactions aroused by an upstaged performance, despite the huge culture gap and language differences.
