Somewhere in America, an army of pre-teen competitive dancers plots to take over the world. And if their new routine is good enough, they’ll claw their way to the top at the Boogie Down Grand Prix in Tampa Bay. But in Clare Barron’s raucous pageant of unbridled ambition and ferocity, these young dancers have more than choreography on their minds, because every plié and jeté is a step toward finding themselves, and a fight to unleash their power. “Dance Nation” is a play about ambition, growing up, and how to find our souls in the heat of it all.
