Rossi leads the BAU in presenting one of his longest tenured cases to a class of college students who are learning about profiling. Through this lecture, Rossi tells the story of an UnSub who was a victim of constant physical and emotional abuse throughout his childhood. After becoming an adult, he began to kill women and remove their wombs. Rossi chases the UnSub up and down the west coast over the course of nearly twenty years, and in the process he shows the class how far the science of criminal profiling has come.
