Emma and Adam have known each other since their teenage years, occasionally crossing paths through various events in their lives. Emma, a dedicated doctor, is wary of emotional attachments due to her demanding career and past experiences. Adam, an assistant working in Hollywood, is heartbroken after discovering his ex-girlfriend is now dating his father. In a chance encounter, they decide to engage in a purely physical relationship, agreeing to avoid emotional entanglements and romantic expectations. The arrangement seems ideal, allowing them both to fulfill their needs without the complications of a traditional relationship.

As time progresses, their casual setup becomes increasingly complex. They start to spend more time together outside the bedroom, sharing personal stories, meeting each other's friends, and supporting one another through tough times. This growing intimacy challenges their initial agreement, leading to conflicts and confusion about the nature of their relationship. Emma struggles with her fear of commitment, while Adam grapples with his deepening feelings for her. The once clear-cut boundaries they set begin to blur, forcing them to confront their true desires and the possibility that their no-strings-attached pact might transform into something more profound.
