The invention of sound (engelsk)

Private detective Gates Foster is a father in search of his missing daughter, and sound engineer Mitzi harbors a secret that may help him solve the case. It's Mitzi's job to create the dubbed screams used in horror films and action movies. But what no one in Hollywood knows is the screams Mitzi produces are harvested from the real, horror-filled, blood-chilling screams of people in their death throes.
