Set in an undisclosed Midwestern American city, Chad (Aaron Eckhart) and Howard (Matt Malloy) find themselves as two middle-management employees from a corporation, sent to work at a branch office far from their home base for a few weeks. With Howard at the helm of a new project and Chad assigned to assist him, they bond over their initial meeting at the airport, sharing a meal and drinks, during which they vent about their troubled romantic pasts.
Their mutual bitterness towards their experiences with women fuels a spiteful revenge plan to target a vulnerable woman, woo her simultaneously, and then end their relationships in unison. The mastermind behind this scheme, Chad, is portrayed as a cruel, manipulative, and misogynistic figure who mistreats his subordinates and peers. In contrast, Howard embodies a more passive character, which ultimately leads to friction between the two as their plans unfold.
Their target becomes Christine (Stacy Edwards), a deaf colleague who, burdened by self-doubt, wears headphones to compel others to engage with her through visual cues rather than verbal communication. Both Chad and Howard take the chance to invite her out, and feeling isolated, Christine accepts their advances. They enter into a deceptive romantic entanglement, each dating her under the guise of genuine affection.
As the weeks progress, chaos ensues at work; a crucial fax Chad was responsible for goes missing, and his presentation suffers due to barely legible documents. These blunders lead to the demotion of Howard, while Chad cunningly assumes leadership of the project by shifting the blame onto the oblivious Howard.
Things escalate when Chad and Christine become intimate, and she falls for him. When Christine discloses her relationship with Chad to Howard, he is compelled to reveal their deceitful plot and his true feelings for her. In disbelief, Christine confronts Chad, only for him to shamelessly admit to the plan. After being met with an enraged slap from her, Chad callously provokes her, leaving her in devastation.
Weeks pass, and Howard eventually seeks out Chad in his apartment, now in disfavor at work with his position diminished while Chad thrives. Although Chad offers to help Howard, he admits guilt over their treatment of Christine, whom he genuinely loved. At this moment, Chad, despite claiming his girlfriend Suzanne has left him, reveals she is still at his apartment, asleep in his bed. He coldly boasts that he executed the entire scheme "because I could," then taunts Howard about the pain they inflicted on an innocent woman.
Stunned and enraged by Chad’s actions, Howard departs, appalled at how Chad exploited him to secure his promotion and cause emotional harm without any remorse. Upon returning to the anonymity of the nameless city, Howard spots Christine working at a local bank. As he attempts to reach out, she pointedly ignores him. Desperately, he calls out for her to "listen," yet his cries fall completely on deaf ears, underscoring the profound consequences of their destructive choices.
