Toronto in the summer of 2010 turns into a fortress for the G20 summit, as leaders of the world's twenty largest economies arrive to set policy alongside corporate representatives. The film documents the security operation built to protect them: exclusion zones carved out of downtown streets, layers of fencing sealing off the meeting site, and roughly 25,000 police and military personnel on the ground, at a cost exceeding 1.3 billion dollars, more than every previous G8 and G20 summit combined. Footage shows unmarked vans carrying plainclothes officers through residential neighborhoods and the pre-emptive arrests of activists who had done nothing more than organize a planned demonstration. Civil liberties lawyers, detained protesters, and residents caught in the security perimeter describe what it felt like to live inside a city treated as a threat rather than a host. The film sets the price tag and the policing tactics against the actual proceedings inside the summit, asking what the security response reveals about how governments weigh dissent against the comfort of visiting heads of state.
