Nat, a young art student in New York City, is struggling to pay her bills when her friend makes a suggestion: why not date a wealthy, older man? He ll pay her rent and give her a monthly allowance – and all that’s required is being his arm candy when he s in town. Sexual favours are optional.

Though more than thirty years her senior, Grant, a corporate finance attorney, seems like the perfect candidate, and within a month, they are madly in love. At least, Nat is . . .

Grant already has a family, whom he has no intention of leaving. When he ends everything, Nat begins to stalk him at work, tracking his phone, spying on his wife, even befriending his daughter, who s not much younger than she is.

But when Grant is found dead in his posh Upper East Side apartment and the police find the murder weapon in Nat’s apartment, she is sure she must have killed her lover; she just can’t remember anything that happened that night.
