At the biggest fireworks competition in the world - L'International des Feux Loto-Québec in Montreal - Maude, Eric, Sebastien and Philippe help their British friends stage an ambitious show, power-packed with over 10,000 effects. The work goes well until the night before the show when a flash flood wipes out their set-up. Then in Berlin, Eric, Benoit, Hugues, and Philippe take on five European teams at Pyronale, the "World Cup" of fireworks. A festival they expect to be genteel and refined turns into a bare-knuckle battle as each team pulls out all the stops to launch the most impressive show and bring home a gold trophy.
