The third permutation of the "CSI" franchise sets up shop in the Big Apple, where taciturn detective Mac Taylor and his new partner, Jo Danville, lead a crime-solving team. Taylor, a retired Marine who believes evidence holds the truth that people may try to cover up, finds balance in Jo's empathy-driven investigative style. Their team includes spirited investigators like Danny Messer and wife Lindsay Monroe Messer, former coroner Sheldon Hawkes, and edgy detective Don Flack.

A shooting and its aftermath drastically change the life of a member of the team.

The team searches for a cyberkiller who seems to be targeting health-care workers; the case turns personal when a suspect mentions Mac's father.

Mac and the team follow the trail of evidence left by a killer after two bodies are found, one at the north end of the city, the other at the south.

DNA evidence contradicts the confession of a scorned woman who claimed to have brutally murdered her cheating husband.
