Brandon is a successful executive living in New York City who is privately struggling with a serious sex addiction. His days are marked by a relentless pursuit of physical encounters, while his nights are filled with the hollow interactions afforded by pornography and emotionless liaisons. Brandon's meticulously controlled world begins to unravel when his wayward sister, Sissy, makes an unexpected visit and moves into his apartment. Her presence is disruptive to his routines, and her needy, volatile nature poses a challenge to Brandon's emotionally detached existence.

Sissy's arrival forces Brandon to confront his behavior and the impact of his addiction. As she tries to carve out a space for herself in his life and leans on him for support, the siblings' complex relationship comes to the fore, replete with unresolved tension and unspoken trauma. Their interactions begin to expose the depths of Brandon's problems, and he starts to lose his grip on the carefully constructed facade of normalcy he's built. With his professional life at stake and his personal life in disarray, Brandon is pushed towards a critical point that demands reflection and a reevaluation of what he wants from life.
