New York is known as the city that never sleeps. On its constantly hustling, bustling streets crime never sleeps either; and nor do the ever-vigilant crime-fighters who strive to solve its murder cases and bring perpetrators to justice using the very latest in forensic investigative techniques. Now, high-tech science comes to the Big Apple as Detective Mack Taylor (Sinise) and his partner, Detective Stella Bonasera (Kanakaredes), lead a team of dedicated, case-cracking experts in the gritty, kinetic city. In DELUGE, six straight days of heavy spring rain threaten to cripple New York. Already several people have been electrocuted by fallen power lines and flooding on some subway tracks has stopped trains. In the midst of all this Mack and his colleagues have no less than three pressing cases to solve: a series of grisly murders in which the victims all seem to have an unusual connection; the puzzling death of a teacher on the upper west side and the suspicious collapse of an entire building - which puts one of the team in deadly danger.
