Jessica Loren, a rookie police officer on her first assignment, is ordered to take the last shift at a police station before it is permanently closed. Her mother pleads with her not to take the job, as her father, also a police officer, was killed while on duty. After assuring her mother that the shift will be uneventful, she reports for duty. Loren surprises her commanding officer Cohen, who demands that she turn around. He leads her on a brief tour, during which he explains that a HAZMAT team will be there shortly to collect evidence that is difficult to dispose of and that she is not permitted to leave her post. Before he leaves, he gives Loren his phone number in case of emergency.
