It tells the story of a struggling President who is persuaded by his confidants to fight with Canada when a local sheriff and his friends get involved.

Local sheriff Bud Boomer and his deputy/girlfriend Honey then prevent the despondent former Hacker employee Roy Boy from committing suicide at Niagara Falls.

The President defends his own belief that the future of the children is more important than war which has caused major decline in his approval rating.

Later that night, Boomer offensively criticizes Canadian beer while attending a hockey game with Honey, Roy Boy, and deputy sheriff Kabral Jabar between the neighboring nations in Niagara Falls, Ontario causing a brawl to break out.

The ensuing riot ends up on the news the next day and catches Stuart's attention which led to everyone getting detained overnight.

In a rescue attempt, Boomer, Roy Boy, and Kabral sneak into a Canadian power plant and cause a countrywide blackout.

After storming up, Stuart takes the operating codes from him required to stop the Hellstorm while accidentally killing Hacker in the process.

Before the final shot of Boomer and Honey's speedboat unknowingly heading towards the waterfall is shown, an epilogue reveals the characters' fates: Moore was inspired by the pro-war sentiment and 90% approval rating for President George H. W. Bush at the time of the Gulf War and wondered if the president could gain public support for war on any country, even Canada.

The scene where the American characters look longingly home at the US across the putative Niagara River is them looking across Burlington Bay at Stelco steelworks in Hamilton, Ontario.

The film has numerous cameos by Canadian actors, including Dan Aykroyd, who appears uncredited as an Ontario Provincial Police officer who pulls Candy over (not for the crude anti-Canadian graffiti on his truck, but its lack of a French translation; Boomer dutifully sprays his truck in French graffiti).
