Horatio Caine, a former homicide detective, heads a group of investigators who work crimes amid the steamy tropical surroundings and cultural crossroads of Miami. His team includes Calleigh Duquesne, a bilingual Southern beauty with a specialty in ballistics; Eric Delko, an underwater recovery expert who knows all the twists and turns of the Florida waterways, and Ryan Wolfe, a former patrol officer who specializes in blood and trace evidence. Rounding out the team is Natalia Boa Vista, the enigmatic DNA specialist, Alexx Woods, the no-nonsense know-it-all coroner and Det. Frank Tripp, a tough yet thorough police officer. Together, these investigators collect and analyze the evidence to solve the crimes and to avenge those who cannot speak for themselves - the victims.
