Josh Abrams, a dedicated and idealistic teacher, goes missing after leaving the inner-city high school at which he is a respected science teacher. Danny finds a bag of heroin in Josh's apartment and when a student from the school comes forward to say that she saw the missing man deep in conversation with the student body drug connection, that is where the focus of the investigation lies. However, it isn't long before a set of incriminating photos of the teacher surface and the team begin to suspect that he may have got a little bit too personal with one of his students.
