An unnamed woman waits in her New York City apartment for the married father with whom she's been having an extended affair. He buys her expensive things she can't afford on her secretary salary, such as designer shoes and a nicer apartment. Despite the monetary benefits of their relationship, she feels that he uses her in much the same way her previous affair used her: occupying precious years of her life, only to wind up single, regardless. She wonders whether her relationship with the man will flourish into anything substantial or if she'll just end up single and older.
As she sits in a chair in her apartment, clad in nothing but high heels, she becomes increasingly frustrated with her situation and grabs a pair of sewing shears that her mother had given her. Despite the size difference, she knows that she is capable of murdering him if she is intentional with her attack. In many ways she feels out of control: her secretary job is dissatisfying, she has few friends, and even her affairs are less and less pleasing. By killing the man, she may yet regain agency in her life.
Likewise, the man understands that this affair has slipped out of his control. As he drinks up the courage, he reckons with what he should do: continue the affair and risk his family, or wash his hands of her and be done. Turning the key to her apartment, the two of them grapple with their murder plans, still undecided as he enters.
