On a sunny June day in London, Clarissa Dalloway, a woman of high society, is immersed in preparations for an elegant party she is organizing for that evening. As she navigates the streets of the city, her thoughts intertwine with memories of the past, particularly her youth and her relationship with Peter Walsh, a childhood friend who still holds a special place in her heart. As the day progresses, the narrative intertwines with the life of Septimus Warren Smith, a World War I veteran suffering from psychological trauma who struggles to find his place in a world that does not understand his pain.
Throughout the day, the paths of Clarissa and Septimus cross unexpectedly, revealing the complexities of life and human connections.

Meanwhile, Septimus confronts his inner darkness, feeling increasingly alienated and desperate.
In this poignant and melancholic journey, the film explores themes of love, loss, and the quest for authenticity in a world that often feels superficial. The party becomes a symbol of connection, where intertwined stories will find their resolution in a convergence of emotions that will transform the lives of all involved.
