One Fine Morning

Sandra Kienzler is a young widow living in Paris, navigating the challenges of raising her daughter, Linn, while also caring for her father, Georg. Georg suffers from Benson's syndrome, which affects his cognitive functions and vision, adding to the weight of Sandra's responsibilities as she balances work and family.

In a park, Sandra unexpectedly encounters Clément, an old friend of her late husband. Despite his marriage and recent return from an expedition to the North Pole, a spark ignites between them, leading to a plan to dine together and explore their connection further.

During a visit to Clément's lab, Sandra and Clément share a moment of intimacy that results in a passionate kiss. This moment marks the beginning of their discreet affair, complicating Sandra's already tumultuous life.

Sandra's mother, Françoise, expresses deep concerns about Georg's deteriorating condition. He is unable to manage daily activities and experiences hallucinations, prompting the family to discuss the possibility of placing him in a nursing home for better care.

With nursing home placements taking time, Georg is admitted to a hospital where Sandra meets one of his former students. This student wishes to reconnect with Georg, and Sandra offers her email as a means for them to communicate.

As the family begins to clear out Georg's apartment filled with books, Sandra rescues a few volumes for herself. She plans to give the remaining books to the former student, signifying her commitment to preserving Georg's legacy.

While in the hospital, Georg frequently mentions his long-time girlfriend, Leïla, raising concerns about his perception of reality. His condition continues to worsen, leading to increased confusion and isolation.

Georg is temporarily placed in a public nursing home, where he experiences confusion and struggles to recognize his family. This prompts the Kienzler family to plan for a permanent move to a private home to ensure better care.

As Sandra's relationship with Clément deepens, it begins to show signs of strain. Clément wrestles with the decision to leave his wife, while Sandra grapples with the reality of being viewed merely as his mistress.

While sorting through her possessions, Sandra finds a small notebook that Georg had used to document his health and a rough draft of his long-desired autobiography. This moment highlights Georg's unfulfilled dreams and deepens Sandra's connection to her father's past.

During a family Christmas dinner, Sandra shares her discovery of Georg's notebook titled 'An einem schönen Morgen'. This revelation not only brings the family closer but also revives memories of Georg's aspirations.

As summer approaches, Clément finally makes a life-changing decision to free himself from his marriage. He returns to Sandra, solidifying their relationship and providing them both with a renewed sense of hope.

The trio—Sandra, Linn, and Clément—visits Georg in his new private residence, engaging him in conversation about a recent trip to Italy. However, confusion reigns as Georg repeatedly asks for Leïla, unaware of his surroundings.

During a heartfelt group activity with other nursing home residents, Georg's family shares a poignant moment singing 'Mon amant de Saint-Jean'. This emotional experience emphasizes the power of music in connecting with Georg despite his deteriorating state.

The story culminates as Sandra, Clément, and Linn ascend the steps of the Sacré-Cœur Basilica. At the dome, they gaze out over the beautiful city of Paris, finding solace and reflection in their intertwined lives and the bittersweet nature of their experiences.
