Detective Mac Taylor is a dedicated crime scene investigator who believes that everything is connected and everyone has a story. He and Detective Stella Bonasera lead a team of crack forensic experts through the gritty and kinetic world of New York City as they piece together clues and eliminate doubt to ultimately crack their cases.A modest home in a suburban Queens neighborhood is the unlikely site of a grisly crime scene: a married couple and their daughter are found brutally murdered. Missing from the scene is the couple's young son, and Mac Taylor and Danny Messer soon uncover signs of a possible kidnapping. Can they find him before it's too late?In a heavily Orthodox Jewish neighborhood in Brooklyn, the body of a devoutly religious man is found ritually displayed on the floor of his synagogue. Stella Bonasera and Aiden Burn initially suspect a fringe fundamentalist group that has had run-ins with the victim's congregation, but the group is led by a charismatic and antagonistic man who does everything he can to stonewall the team's investigation. Two very different crimes, with one thing in common: CSI investigators who won't stop until they uncover the truth.
