Devin and Nadia team up with Bounce, Pema and Marcus as they all travel to Northern Ontario to watch their parents present to the Summit of World Leaders.

A swarm of politicians, lobbyists, corporate bosses and protestors have all converged on the summit to get their messages heard. A tragic accident just hours before their parents' presentation plunges the kids into their biggest mystery yet and sets them on the trail of a murderer bent on stopping their parents' controversial message from being heard. It's a fight against the planet's power players as the kids dive into the world of politics, uncovering how government works, the history of democracy, the influence of lobbyists and corporations on politicians and the potential of civil society to change it all.
