Take a punt on this immaculately poised and nihilistic black comedy thriller which carries its chilly premise across the finish line with tremendous composure and style.

Olivia Cooke and Anya Taylor-Joy give deliciously dead-pan performances as a pair of teenagers born to a world of wealth and privilege and bred to be social show ponies.

With the former saddled with a creepy and controlling stepfather, a plot is hatched to dispatch him. The film is dedicated to the late Anton Yeltsin who plays the local drug dealer whom they rope in to help.
