Okaro tasks the relief with policing a sell-out gig at the Bombastic nightclub. All goes well until Keane oversteps the mark and causes a mass brawl when she tries to arrest a punter for possession of drugs. As the brawl begins to cool down, a second disturbance breaks out, forcing Hemmingway to convince the club's security to let the entire queue in the club in order to prevent further violent disruption. When a young man is crushed at the front of the ever-increasing crowd, Valentine tries to prevent further casualties and asks the crowd to step back. As the revellers converge on an upstairs balcony, the balcony collapses, along with the sound system and a number of lighting rigs. (thetvdb.com)
