Replying...
Intro. Jack is born on a night so cold that his heart freezes. To save him, Dr. Madeleine places a mechanical watch on his chest. But he warns her of three rules: don't touch the needles, don't get angry, and never fall in love, because love could break her heart. Years later, Jack meets Miss Acacia, a young singer, and falls madly in love. His heart begins to fail, and he sets off on a journey to find her. He finally finds her in a circus, but their love is so intense that her fragile heart cannot resist it. When Jack enters the circus, he becomes part of the show. His act is unique and mysterious: he appears dressed in an elegant suit, showing the metallic glow of his heart-clock, which beats and sounds like a cuckoo. The audience watches in amazement as Jack moves the needles on his chest to the rhythm of the ticking and spins small gears that release sparks of light.
