In Sexy Evil Genius (now available on DVD and On-Demand) a group of strangers are lured to a downtown LA bar by Nikki, the ex-girlfriend they all have in common. Fresh out of prison for the murder of her last ex-boyfriend (who couldn’t attend on account of being dead), Nikki is mysterious about her intentions and her current and former lovers soon realize they are all caught in one of her brilliant, mischievous mind-games with possible deadly consequences. Or maybe a gang-bang?
I once went on a ski trip with an ex and unbeknownst to me, she invited a few of her other exes. It didn’t end in murder though I wanted it to.
