Welcome to Palomar City, a tightly-packed, overpopulated American mega-city. Over the last sixty years, a series of traffic control devices known as Gates have transformed this thriving metropolis into a pressure cooker of political and socio-ethnic tension that is on the verge of exploding. One of the only groups with unrestricted passage through the Gates are the emergency medical teams, nicknamed "The Gatecrashers, " who find themselves in the middle of a building conflict that threatens to tear Palomar City apart once and for all.In the Ganesa ambulance dispatch garage, Gatecrasher Hex Spencer is suiting up for another night shift when her boss saddles her with a ride-along journalist named Archie McAlester. It's gonna be a long night.
