When an innocent man is brutally attacked and beaten to death by what looks like a monster in a black cape, the CSIs are called to investigate, only to learn that a similar attack took place minutes later. As the crime spree continues, the team follows the trail of evidence until Greg interrupts a beating in action and must make a difficult decision that could impact his life forever. Kevin Federline and Victoria Recano guest star.
