When the Chinese Communist Party alters its promise of autonomy to Hong Kong - handed back to the Chinese government from British rule in 1997 - teenager Joshua Wong decides to fight for his homeland. Rallying thousands of kids to skip school and occupy the streets, and without a long-term plan but with passion to spare, Joshua becomes an unlikely leader in Hong Kong.

A remarkable portrait of courage, resilience, and the propulsive power of youthful idealism, "Joshua: Teenager vs. Superpower", the winner of this year's Audience Award at the Sundance Film Festival, is a chronicle of one young man risking his own future for a greater good.
