V is for Vagitus (The Cry of a Newborn Baby)

In New Vancouver, A.D. 2035, women must petition the government for permission to bear children. Lainey, an officer, successfully petitions for one, but discovers she is infertile. She and her robot partner, Nezbit, break into a facility to hunt for "mentals". They discover a family which Nezbit subsequently kills; he then beheads the family's baby. Lainey's boss, Stoker, enters and criticizes her, due to her sympathizing with the family. The baby's head turns out to be alive and possessing some psychic power, as it proceeds to blow up Stoker's head, while the dying father tells Lainey that she is its mother now.
