Former NBC News fixture Chris Hansen leads a team of correspondents on this series that explores the world of crime, mystery and drama through real-life criminal cases. Hansen brings to the show a modified version of a long-running segment he did at NBC. In "Hansen vs. Predator," he helps bring down predators who use social media to target children. Dirty politicians, financial scammers and celebrities are also targeted by Hansen's investigations. Hansen anchors the show from the streets of New York City, while most of the correspondents are based at the Los Angeles newsroom.
