Carla, seven-months pregnant and with four children already from various men, working as a cashier in Bath, England, is contacted by Heather; best friends at school while pre-teens during Year 7, they meet up having not spoken in years. Heather - who has been trying unsuccessfully to become pregnant with her husband, Simon - asks Carla to kill Simon as he has been cheating on her. Heather offers her £50,000, which Carla gleefully negotiates to £75,000. In Heather's house, Carla and Heather talk about how she will kill Simon. Carla plans to make it look like a botched burglary, admitting to having committed house burglaries in the past. Carla notices that Heather has framed insects on the wall, one of which is the tarantula hawk, a wasp which buries an egg into a tarantula and grows by eating the spider from the inside out avoiding any major organs, meaning the victim stays alive; the young wasp eventually crawls out of the tarantula's abdomen, leaving it to die. While they continue planning the murder, Heather talks about how horribly Carla - a brutal school bully - had treated her when they were young, including viciously beating her face in a school store room. Carla tells her that their early friendship eventually disgusted her, growing to despise Heather for having a normal life while hers was filled with brutality from her own father. Concluding the murder plan, Heather shows Carla a photo of Simon; Carla recognises him as "James", revealing that she is also a prostitute who has had Simon as a regular customer for some years, taking cash in return for unprotected sex that incidentally impregnated her. Heather then chloroforms Carla. Carla awakes bound and gagged to a chair and Heather talks about the last time Carla had attacked her in school, having two other girls hold her while Carla raped her with an object, destroying Heather's reproductive organs. She then threatens Carla with death, that she will take her child from her, and reveals that she has already killed Simon. Heather pushes Carla to think that she is going to kill her, so acting on impulse Carla stabs Heather in the abdomen just as Simon opens the front door and enters the room. As the blood-soaked Heather dies in his arms, neighbours look in the window to see the entire situation, including Carla still holding the murder weapon; Heather had left them a note begging them for help, writing "I think my husband and his mistress are going to try and kill me". The police arrive seconds later. The final shot is a tiny wasp crawling out of Heather's body and flying away. (thanks to Wikipedia)
