Aortic tenderly navigates the emotional journey of a young man in the aftermath of a heart surgery. The narrative unfolds within the confines of a hospital's broom cupboard, where Jack musters the courage to leave a heartfelt voice note to an old friend. The film visually juxtaposes the feeling of claustrophobia with a rose-tinted memory, lost within a vast countryside landscape. Aortic blends themes of nostalgia, vulnerability, and the human experience of coping with a life-altering event.
