Stalker, an art student in New York City, is struggling to pay her bills when a friend makes a suggestion: Why not find a sugar daddy - a wealthy, older man who will pay her for dates, and a monthly allowance. All that’s required is to look pretty. Sexual favours are optional.
Gabe, a handsome finance attorney, seems like the perfect candidate and within a month they are madly in love. At least, Nat is - Gabe already has a family, who he has no intention of leaving.
When he abruptly ends things, Nat can’t let go. She begins drinking heavily and stalking Gabe and his family. Their supposedly mutually beneficial arrangement devolves into a nightmare of deception, obsession and, when a body is found near Gabe’s Upper East Side apartment, murder.
