A young boy is captivated by the sight of a traveling circus that sets up near his small town. He sneaks into the big top and becomes transfixed by the clowns, feeling a mix of amusement and unease at their antics. This fascination with clowns stays with him as he grows up and becomes a filmmaker. Hoping to explore the world of clowns more deeply, he sets out on a journey across Italy with a small crew. They visit a variety of circuses, speak to performers, and examine the history and cultural significance of clowns. Through interviews with current and former clowns, they gain insights into the life behind the greasepaint and the laughter.

As the filmmaker digs deeper, he uncovers the complex layers that make up clown artistry, from the training and discipline required to the emotional struggles performers face. Alongside these discoveries, he reflects on his own childhood memories and the impact clowns had on him. The film weaves a tapestry of personal reminiscence, documentary footage, and imaginative re-enactments that delve into the heart of clowning. Without reducing the clowns to mere comic relief, the film ennobles their craft and sheds light on the poignant, often melancholic lives of those committed to making others laugh.
