Through an interview with Kiarostami in the Aran Islands and interviews with film critics and scholars at Cannes, the director examines Kiarostami's themes and methods. The director also profiles Kiarostami as a poet and a photographer.

Kiarostami as we have never really known him before, despite the transformative power of his many movies. Filmmaker and close friend Samadian avoids the talking heads of so many artistic memoirs to offer more candid clips of Kiarostami the man: lover of poetry, convivial with friends, engaging landscapes on and off screen, laughing with other artists. The artist and visionary emerges more clearly but so does a loving, wondrous man whom we will miss now as much as the auteur.
