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.

Mac is determined to seek justice when a 14-year-old boy is shot in front of his 12-year-old brother.

While at home recuperating from an injury, Mac witnesses mysterious behavior that leads to a murder.

On the 10th anniversary of 9/11, Mac and the team remember specific moments from that day.

A civilian who has something against the Marines is the prime suspect when a member of the corps is killed during Fleet Week; Aiden (Vanessa Ferlito) returns to help the team find crucial evidence to catch a serial rapist.
