Endless trash and seething heat feed the chaos on day two as performers are pelted with debris and Limp Bizkit riles the crowd to its breaking point.

Tainted water and price gouging mar day three. Fear grips the finale, fires spread, and the mob takes over. Later, sexual assault allegations emerge.
