Backgammon is a psychological thriller that opens with Lucian, his girlfriend Elizabeth, and their friend Andrew-going to spend a weekend at a country mansion. They’re greeted by Miranda, Andrew’s older sister, and Gerald, the weirdly annoying, Baudelaire-obsessed boyfriend she tries in vain to control. Overwhelmed by Gerald’s antics, Andrew and Elizabeth split. But Lucian stays. He doesn’t like being cowed-and it doesn’t hurt that there’s a simmering sexual tension between him and the flighty, flirtatious Miranda. When Gerald, having goaded Andrew into an alcohol-fueled poker marathon, explodes after losing everything, Miranda finally gives him the boot. Or so she and young Lucian hope. But as they begin to dance around each other, their surroundings show increasingly threatening signs that Gerald may never have left.
