In „Echo of You”, filmmaker Zara Zerny tenderly portrays nine elderly Danish people. They talk about their love lives, growing old, grief, and their perspectives on life and death. The eloquent, candid and sometimes poetic speakers are filmed at home, seated in a chair or in bed. Zerny intercuts these static shots with artistic, sometimes dreamy or abstract representations of their testimonies. Old home videos are also projected onto the interviewees, reflecting a different, bygone existence.
