Read the complete plot breakdown of Obsessed (2009), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

The film begins as an African-American family settles into their new home, featuring Derek Charles (Idris Elba), his wife Sharon (Beyoncé Knowles), and their baby, Kyle. Upon arriving, Sharon removes the sold sign, and they explore their new surroundings, engaging in a playful game of hide and seek in the vacant rooms, culminating in an intimate moment in their bedroom as they await the arrival of the moving truck.

As the movers show up, Sharon takes charge of organizing their new living space while Derek heads to his office. There, he encounters a striking blonde, Lisa Sheridan (Ali Larter), a temporary worker at the firm. Their initial interaction sparks an undeniable chemistry, with Derek finding himself both intrigued and unsettled by her attention. When Lisa misplaces a bundle of files in the office, their hands accidentally touch, igniting a tension that Derek tries to ignore as he returns home to Sharon.

Despite his efforts to keep things professional, Lisa becomes an increasingly prominent presence in Derek’s life at work. She quickly proves herself to be extraordinarily capable, garnering compliments from colleagues and drawing Derek’s friend’s attention to her attractiveness. After confiding to Ben, one of his pals, that things seem to be getting uncomfortable with Lisa’s persistent clinginess, Derek decides it’s time to address the issue with Human Resources.

After a disastrous office Christmas party where Lisa inappropriately corners him, Derek attempts to set boundaries. Tensions escalate when he finds Lisa unexpectedly in his accommodation one night during a work retreat, leading to an unexpected and regrettable night filled with poor decisions. The next morning, he faces the fallout of his actions, culminating in a series of misunderstandings that unravel his marriage.

As the drama unfolds, Derek attempts to reconnect with Sharon, who is dealing with her own family crises. However, he is unaware that Lisa has her schemes, which escalate to alarming levels. After an incident involving their baby, which ends with Derek and Sharon rushing to the hospital in desperation, the stakes become life-threatening.

In a thrilling climax, Sharon confronts Lisa in their home, leading to a fierce physical confrontation that spills from the bedroom down the staircase and into the attic. In an unexpected turn of events, Sharon’s compassion leads her to save Lisa from a fatal fall—until in a deadly struggle, Lisa ultimately meets her demise. The emotional toll on both families is profound, leaving behind shattered relationships and uncertainty about the future.

In the aftermath, Sharon’s resilience shines through as she walks out to meet Derek, their bond possibly stronger than before. The film closes on a haunting note, highlighting the fragility of love intertwined with obsession.
