Monster is a 2003 biographical crime drama film that tells the story of Aileen Wuornos, a real-life sex worker who was convicted of murdering seven men and was executed in Florida in 2002. The film stars Charlize Theron in a transformative performance as Aileen, and Christina Ricci as Selby, a young woman with whom Aileen forms a complex and intense romantic relationship. Set in Florida during the late 1980s and early 1990s, the movie explores Aileen’s troubled past, her descent into violence, and the emotional turmoil that accompanies her crimes.
The film begins with Aileen contemplating suicide, reflecting on her childhood filled with abuse, abandonment, and rejection. Just as she is about to end her life, she walks into a gay bar and meets Selby. The two quickly develop a bond. Selby is curious, lonely, and sheltered, while Aileen is rough, impulsive, and desperate for love. Their connection becomes the central emotional thread of the story, providing Aileen with the sense of affection and belonging she has never known.
In an effort to support their relationship, Aileen continues to work as a sex worker. But one night, a client brutally assaults her, and she kills him in self-defense. This traumatic event becomes a turning point in her life. Afterward, Aileen begins murdering other clients, claiming that each one was trying to hurt her. The film leaves the audience questioning her motivations: were the killings acts of survival, vengeance, or the result of deep psychological damage?
As the bodies pile up, the couple’s life starts to unravel. Selby becomes increasingly suspicious and worried, yet she continues to rely on Aileen financially and emotionally. Aileen, on the other hand, tries to justify her actions as a way to protect herself and give Selby a better life. However, the world closes in on them. The police begin investigating, and Aileen becomes paranoid and desperate.
Eventually, Aileen is arrested, and Selby is pressured by law enforcement to betray her. In an emotionally powerful moment, Aileen takes full responsibility to protect Selby, knowing it will seal her fate. The final scenes show Aileen being tried and sentenced to death, all while maintaining her belief that she did what she had to do.
Monster is not just a crime film; it is a psychological portrait of a damaged soul shaped by trauma, poverty, and desperation. Charlize Theron’s portrayal is haunting and raw, making the audience feel both horror and empathy. The film challenges viewers to consider how society treats the broken, and whether monsters are born—or made.
