`True CSI' gives viewers a chance to examine the evidence of a real homicide case for themselves by bringing the cameras to the scene of the crime. The programme evaluates the evidence and tests opposing theories by demonstrating what might have happened in the events leading up to the crime from a variety of angles. Each episode showcases one homicide case, following it from the collection of forensic evidence through all stages of the investigation until clever detective work and state-of-the-art forensic science reveal the truth.
