Season 10: Episode 18 - Field Mice

Field Mice: When a group of three high school CSI Explorer Scouts are given over to Wendy and Hodges in the lab for training, they go over an open but cold case involving a woman who is found dead in a burned out building, but without a burn on her body.  However, as they walk through the teaching case they begin to discover clues that may lead to an unexpected case resolution.  Story will be told in flashbacks/fantasy segments in which the audience will see how Hodges and Wendy see themselves.  Instead of seeing Langston or Catherine in the flashbacks we see Hodges and Wendy acting like Langston and Catherine, solving the crimes as CSIs.
