Iris is a young girl grappling with depression and anxiety, feelings dramatized through a journey into a surreal inner world. Descending along a version of the mythical river Styx, reimagined here as the boundary between the real and the imaginary, she faces the manifestations of her own fears and inner demons. Floor by floor, Iris fights her way through this shifting mental landscape, confronting the doubts and worries that torment her in a deeply personal battle for peace.
