Entering their third season, the Miami CSIs continue to work to rid the streets of crime using state-of-the-art scientific techniques and back-to-basics police work. The team suffers a personal loss this season as Tim Speedle is gunned down while investigating a murder/kidnapping. Horatio hires Ryan Wolfe, a patrol officer with Obsessive Compulsive tendencies, to round out their investigative squad. Facing their most explosive season yet, the team investigate piracy, car-jacking, gun-play, homicides involving snakes, and a tsunami.
