Collateral Damage tells the story of family man and firefighter Gordon Brewer (Arnold Schwarzenegger), who is plunged into the complex and dangerous world of international terrorism after he loses his wife and child in a bombing credited to Claudio "The Wolf" Perrini (Cliff Curtis). Frustrated with the official investigation and haunted by the thought that the man responsible for murdering his family might never be brought to justice, Brewer takes matters into his own hands and travels to Colombia to track down the terrorist.
