Lexi Mazur is a depressed, alcoholic pill-popper whose only joy has become her reality TV shows, often fantasizing that the people on TV are a part of her world. After her boyfriend, Steve, leaves her, she fixates on the show Socialites and its star, Magnolia Artois, following every facet of the girl’s life on social media in the hopes of befriending and becoming more like her.

But stalking isn’t new to Lexi. She ultimately won over her ex Steve by following and manipulating every minute detail about him so he’d fall for her. In fact, she landed her other ex-boyfriend Jeremy in the same way. Being a pharma rep, she’s used to manipulation to get doctors to buy her drugs, along with the perk of saving pills for herself.

But what happens when the stalker gets stalked?

Recently, Lexi has felt someone watching her: in her apartment in Queens, at her job. At first, she thinks her mind’s playing tricks, but the watcher is behaving just like she would. And soon they begin leaving threatening clues like she starts to do to Magnolia once her obsession grows more dangerous. Is it one of her exes out for revenge? Her only real friend from childhood who she’s always had an unhealthy rivalry? A detective who may have figured her out? The reality star Magnolia trying to turn the tables? Or even someone she might not know?

Lexi learns the only way to beat her stalker is to use her own stalking prowess to outsmart them at their own game. But has she finally met her match?
