Brain on Fire

It's not supposed to happen. Be prepared when it does.

Based on the best-selling memoir, "Brain on Fire" is a gripping and emotional drama that follows the true story of Susannah Cahalan, a young and ambitious journalist working at the New York Post. The film stars Chloë Grace Moretz as Susannah, who delivers a powerful and convincing performance as a woman who suddenly finds herself plagued by unexplained symptoms.

As Susannah's condition worsens, she begins to experience terrifying hallucinations and debilitating seizures. These symptoms cause her to spiral into a state of confusion and despair, leaving her unable to work or maintain her relationships. Despite her best efforts to find answers, Susannah's doctors are unable to diagnose her condition, leading to a rapid descent into insanity.

Thomas Mann plays Stephen Grywalski, Susannah's boyfriend, who becomes increasingly concerned about her well-being as her symptoms worsen. As Susannah's condition becomes more severe, Stephen must navigate the challenges of supporting her through her illness while also dealing with the emotional toll it takes on him. Together, they embark on a journey to uncover the truth behind Susannah's mysterious illness and find a way to stop its progression.
