FRANK SEARCHES FOR A FEMALE SERIAL KILLER AND HER LOVER AFTER THE PAIR ESCAPE FROM PRISON.

Inside Garrison Women’s Prison, Juliet “Sonny” Palmer, and her cellmate/lover, Janette Viti, a pretty 24-year-old, overpower a guard, steal his uniform, and make their way to a security booth. There the couple surprise another guard and force him to remove his uniform. As the guard does so, he reaches for his ankle holster and, in a flash, shoots Janette. Sonny grabs a nightstick and subjects the guard to a brutal beating. When she stops, she realizes Janette is unharmed. The bullet, they realize, flattened itself on the shield attached to Janette’s stolen uniform. Examining the spent slug, the pair notice what looks like the silhouette of a human face. The women move on.

Frank meets with Warden Kellard at the prison. Kellard labels Sonny a serial killer, as she beat her stepfather to death with a pipe, used an andiron on her husband, and has now clubbed a guard to death. Frank examines a map of the surrounding area. He accurately predicts that the fugitives will ditch their getaway vehicle. But Frank is puzzled as to why Sonny chose to escape, as she is eligible for parole in four month’s time.

Sonny and Janette overpower a motorist, Chris Taylor, and take command of his vehicle. The pair stop at a remote house for purposes unknown. They are disappointed that no one is home and leave the scene with Taylor still tied-up in the back seat.

Frank studies Sonny’s case file. He concludes that Sonny crosses over into violence only to protect others, noting that her stepfather was abusing her younger sister, and that she miscarried the same night she murdered her husband, indicating domestic violence. Frank also concludes that Sonny escaped as a means of protecting something else as yet unknown. That night, Sonny and Janette get a room at a motel. As Janette examines herself in a mirror, we see that she is, in fact, quite pregnant. A motel maid discovers Chris Taylor bound and gagged in the women’s room. He tells Frank, Watts and Kellard about Janette’s pregnancy–a revelation that catches the men by surprise. Frank concludes that one of the prison guards is the father. He zeroes in on Ernie Shiffer, an African-American man. Shiffer admits he raped Janette in the infirmary while she was under sedation.

Janette and Sonny make their way to a clinic. A sonogram reveals trouble, but before a practitioner can voice her concern, Sonny learns that the guard she blugeoned died from his injuries. The pair leave the clinic. Watts tells Frank that the nurse spotted a total placenta previa–meaning Janette could bleed to death if she delivers outside a hosptial. Frank eventually zeroes in on the mysterious house the women visited earlier. When he arrives at the scene, a car driven by Sonny bears down on him. The car swerves at the last moment, missing Frank. Shortly thereafter, Janette experiences contractions.

Frank learns that Sonny once worked at a train yard in town. Believing the couple might attempt to flee by train, he makes his way to the yard. There he pinpoints the train the women would most likely use for their getaway. But Sonny gets the drop on Frank and takes him prisoner. Frank tells her he knows the identity of the man who raped Janette. This sends Sonny into a rage. He also informs her of Janette’s medical condition. Sonny tells Frank that the child is a “miracle baby”–God’s child.

Inside the boxcar, Janette’s contractions continue–as does her bleeding. Watts accompanies a SWAT team to the train yard, and the boxcar is surrounded by armed men. When Sonny uses Frank’s cell phone to demand a doctor, Watts patches through the nurse from the clinic. The nurse tells Janette she is aware that she was raped by the prison guard. When Janette reacts, Sonny snatches away the phone and demands immediate medical attention. Two police officers don paramedic uniforms and approach the boxcar. But Frank intervenes, warning Sonny…
