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.

When a powerful gang's leader is killed, the CSIs must find the killer before a street war with a rival gang breaks out; Mac seeks help from the gang's co-founder (Edward James Olmos), who he put behind bars years earlier.

A jewel heist at a powerful attorney's penthouse takes a bizarre turn; the case leads the CSIs to a seemingly unrelated man in the morgue.

When a badly decomposed body is found in an abandoned car, the team must face a killer who is using his victims' parents to manipulate crime scenes.

With a sniper on the prowl, Mac is forced to relive a brutal abduction that produced a deadly foe.
