Alice Lowe (Sightseers) is a triple threat as the writer, director and star of this pitch-black comedy about a pregnant woman whose unborn child psychically spurs her on to murder.

Ruth (Lowe) is seven months pregnant, and like many expecting mothers she believes that her baby is speaking to her through an inner voice - the only difference being that this particular tot is telling her to go on a killing spree.

Still mourning the death of her husband just months before, Ruth allows her baby to coach her on murder techniques and push her onward in a quest to dispatch people who stand in her way, from a pet shop owner to a DJ to a lonely businesswoman.

Through all the carnage, Ruth's bulging belly serves as a perfect alibi - after all, who would ever suspect a cold-blooded killer could be lurking behind the sweet, glowing visage of a visibly pregnant woman?
