People are disappearing. Cooper Riley, a psychology professor, doesn't make it to work one day. Emma Green, one of his students, doesn't make it home. When ex-cop Theodore Tate is released from a four-month prison term, he's begged by Emma's father to help find his daughter. After all, Tate was in jail for nearly killing her in a drink-driving accident the year before, so Tate owes him. Big time. What neither of them knows is that a former mental patient is holding people prisoner as part of his growing collection of serial killer souvenirs. Now he's trying to acquire the ultimate collector's item - an actual killer. The further Tate looks, the more he keeps coming back to Grover Hills, the mental institution on the outskirts of the city that closed down three years ago. Bad things happened there over the years, down in the basement which the patients called the Scream Room. Tate is going to have to delve into Grover Hills' past if there is any chance of finding Emma Green and Cooper Riley alive.
