"Heart of the Machine" is a movie released in France on February 5, 2014
On the coldest day of the year, a life came into the world, but the baby's tiny heart froze. In order to save the baby's life, Dr. Madeleine, who delivered the baby, put a heart made of a cuckoo clock (a mechanical heart) into the baby's chest cavity, saving him and "repairing" him. The baby's mother didn't show up, so Madeleine adopted him and named him Jack. Dr. Madeleine took the trouble to tell Jack that he must avoid any strong emotional ups and downs, lest his "mechanical heart" can't bear it, so he can't be angry, especially avoid falling in love. On Jack's tenth birthday, Madeleine finally agreed to take me to town. Everything in this city is so new that Jack meets a young singer, Acacia, who is performing on a street corner. The girl's voice made Jack feel hot, and the cuckoo clock in Jack's heart began to grow louder.
