Briscoe (Jerry Orbach) and Green (Jesse L. Martin) investigate the murder of a high school English teacher. Their prime suspect is shy student Fiona Reed (Stephi Lineburg), a troubled teenager who, by all accounts, is the product of a miserable, abusive home environment. Digging a bit deeper, the detectives and lawyers McCoy (Sam Waterston) and Southerlyn (Elisabeth Rohm) make the startling discovery that Fiona is not all that she claims to be -- and is not, in fact, even a teenager. ~ Hal Erickson, Rovi
