Prevenge

A pregnant widow, believing herself to be guided by her unborn child, embarks on a homicidal rampage. Characterized as a dark comedy slasher film, it follows Ruth (Alice Lowe), a woman convinced that her foetus is compelling her to murder and seek revenge for the death of her husband in a climbing accident. As she tracks down those involved in the accident, Ruth kills several people, including a reptile shop owner, a DJ, and a lawyer, before giving birth to a normal baby girl, leading her to realize that her foetus was not the psychopathic entity she thought it was.
