DESC: The first of two spinoffs launched by the hugely popular television series CSI: CRIME SCENE INVESTIGATION, CSI: MIAMI introduces a new cast of crime fighters operating from a forensics lab unit in the tropical climes of southern Florida. David Caruso (NYPD BLUE) anchors the series as tortured homicide detective Horatio Caine, who leads an investigative team that includes a Southern-belle ballistics expert, Calleigh Duquesne (Emily Procter); an underwater recovery expert, Eric Delko (Adam Rodriguez); a no-nonsense coroner, Alexx Woods (Khandi Alexander); and an idealistic cop, Ryan Wolfe (Jonathan Togo). While sharing its parent show's penchant for grisly crime reenactments, the spinoff places more emphasis on police work than science, and boasts a flashier cinematographic style that befits its sun-kissed and stylish Miami locale. This collection presents all 25 episodes of the series' fourth season.
