Fringe - S01E02

A woman dies after giving birth to a bizarre baby who ages rapidly and dies four hours later. This reminds Walter of a project he researched with his colleague Dr. Penrose. It reveals that Dr. Penrose has made a major breakthrough; he created a subject,having it to kill prostitutes to cut out their pituitary gland, so he can complete his project. Agent Dunham finds out the crime scene, and Peter saves a girl, but Dr. Penrose escapes.
