Two young boys, a Caucasian and a Black, go missing. Later, a known pedophile (played by Alan Tudyk) who lives in the neighborhood is found to be an arson victim. In an attempt to extract his confession, Brass and Grissom ask for the pedophile's help in catching the boys' abductor. Meanwhile, Brass questions the boys' families and is left to sift through their complicated family backgrounds. However, the case turns out to be much more complicated than Grissom or the rest of the CSI team ever expected.
