Claudio's house is a magical place where every room is a world of colors and sensations that set the imagination free. A circus. He's acrobat, performer, circus artist, capable of turning every moment into a scene. Claudio has lived for the stage his entire life, and when the audience disappears and his children grow up, life beyond the spotlight becomes the hardest challenge of all. Between attempts to reinvent himself, old acts to dust off, and new ideas to stay afloat, he faces the weight of time, loneliness, in a world moving far too fast. Ironic, tender, and deeply human, "Sul filo" is the journey of an artist, balancing between laughter and melancholy, telling what it means to keep existing when the spotlight fades.
