Montreal-based Groupe Fiatlux-Ampleman (GFA) is chosen to put on a fireworks show at the world's largest winter festival, "Carnaval," in Quebec City. But moments before the show starts, head pyrotech Philippe struggles to light the warning shell. Later, GFA participates in the festival's closing parade with a custom float that spits fire and launches fireworks. The show, however, is cut short as high winds prove dangerous. Philippe and Sebastien head to Valencia, Spain to learn from the best of the best during the "Las Fallas Festival."

GFA puts on not one but two New Year's Eve events simultaneously: one in Quebec City, and one in Rio de Janeiro, where Sebastien worries about his own safety at the world's biggest fireworks show. Philippe joins Maude and Eric in Barcelona to shop at a famous fireworks factory and test out some of the world's best pyro. And Philippe and Sebastien learn from the pros in Valencia and take part in "La Crema" - the burning of huge and elaborate sculptures in the public square.

GFA endures public humiliation when human error puts a damper on the company's most important shows and Quebec's biggest national holiday, St-Jean-Baptiste Day.

GFA reaches their breaking point when thunderstorms put a damper on their back-to-back shows on a lake in Ste-Agathe. As the pyros battle wind and water, mishaps quickly multiply and suddenly everyone's safety is at risk.

Maude aims high as she pitches GFA to the client responsible for hiring the pyro company for Canada Day at Parliament Hill. But when circumstances beyond her control push the fireworks choreography out of synch, Maude ends up eating humble pie as her client looks on.

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.

At an international competition in Blackpool England, the team fights hard to live down their defeat in Berlin, but their shot at a trophy is going to depend on flawless help from the locals.

In Campeche, Mexico, Philippe and Sebastien are called on to rig one of the most extraordinary installations of their careers - cramming the roof of a historic 16th century cathedral with explosives. Working with one of the country's top pyrotechnic artists, they find out that doing fireworks "Mexican style" - means breaking all the rules. In Korea, Eric, Philippe, and Benoit take part in one of the most spectacular fireworks events ever staged. Over a million spectators witness an incredible, cutting-edge pyro extravaganza, with shows by Japan, Portugal, and Korea. The astonishing and innovative effects leave the boys from GFA shaking their heads in amazement and determined to up their own game... starting now.
