Wide meadows, romping in the woods and building cabins. Leo (12) spends the autumn holidays with big sister Noémie and cousin Emil on Grandma Marlies' farm. However when Leo is surprised by what Grandma Marlies calls big news, Leo faces an identity crisis. "I am Leo" immerses itself into the emotional world of a child who is on the way to discover their gender identity. A film about expectations that overwhelm, about thoughts that restrict and about the courage to find yourself.
