Beginning with a spectacular murder at the Statue of Liberty and ending with an unusual plea from a bank robber, the fourth season of “CSI: NY” moves along at a quick, exciting pace that belies its almost 15-hour run time. Spread over six discs, all 21 episodes–which originally were televised during the 2007-2008 season–are included. Led by head CSI Mac Taylor (Gary Sinise), the core group of Stella Bonasera (Melina Kanakaredes), Lindsay Monroe (Anna Belknap), Danny Messer (Carmine Giovinazzo), Detective Don Flack (Eddie Cahill), and Dr. Sheldon Hawkes (Hill Harper) returns to solve compelling and often ghastly crimes.
