"You have a gem of a great idea, if you can perfect it," Joseph Henry of the Smithsonian Institute tells Alexander Graham Bell when he presents his theory for the invention of the telephone. When Thomas Watson and Bell begin their work for a multiple telegraph, Bell becomes convinced that he can send the complex sounds of human speech over a wire from its vibrations. Mr. Hubbard, the financier of the telegraph project, laughs when Bell first tells him about the idea for the project and says he will not finance it. Frustrated, Bell and Watson begin to work on the telephone while working on the telegraph without Hubbard knowing it. Bell is constantly inspired by his deaf students and longs to teach them to speak and communicate. His first dedication had always been to be a teacher of the deaf. But, as Bell becomes more and more engrossed in making the telephone invention work, he has little time to work with the students. As the inventors experience triumph in transmitting sound while playing with the telegraph, Bell is distressed to learn of a student, David, who is giving up and going home because he is frustrated with his inability to speak. He meets David at the train as he is leaving to convince him to stay and keep trying, but David refuses. Bell is greatly disappointed in his failure to help the boy and in the unsuccessful attempts to make the telephone work. Bell is frustrated and tired. As he rests on a park bench, his spirit is renewed when a mime communicates with him. He realizes he could never fail if he keeps trying. He and Watson continue working on the telephone with great enthusiasm. Finally, the telephone experimenting works as sound is transmitted through a tube. Watson clearly understands Bell when he says, "Watson, come here. I want you." As they share the joys of success, school begins again. Bell is rewarded by the return of David who has practiced all summer and knows he can succeed, too.

Even as a young boy, Beethoven marched to the beat of a different drummer. Trained in the traditional music methods by his father, Beethoven was an accomplished pianist by the age of 12. But he yearned to try new sounds and persevered until audiences heard his music. By his early twenties, this persistent young man performed for Joseph Haydn, who compared him to the great Mozart. Sadly, Beethoven began to lose his hearing, but he threw himself even more deeply into his music, composing "Fur Elise," "Sonata Pathetique" and the dramatic "Fifth Symphony" years later, audience members heard what he could not and leapt to their feet in ecstatic appreciation for such passionate music. His creativity gave the world then, as it does today, music that stirs the soul. The video begins in 1827 with 30,000 people paying tribute to the great Beethoven in Vienna, Austria. Then the video switches to his life as a child. Beethoven was driven by his father without patience and love to practice playing the music of Mozart and Haydn on the piano; however, Beethoven preferred to improvise and play his own style of music. This enraged his father as it did many symphony patrons later in life. Beethoven was honored to be asked to move to Vienna and have Haydn as his instructor. After years of playing for royalty, Beethoven was frustrated that all the audiences wished only to hear music from Mozart and Haydn. So, Beethoven decided to move to the countryside where he could compose music as he wished. While living in the countryside, Beethoven noticed his hearing loss was getting more severe and feared going deaf. The world was going through a revolution. The America Colonies threw off the British Empire, and common people replaced the King and Queen of France. Beethoven believed that since the world was changing all around him that music should change also. Beethoven's performances were not embraced by the majority because of his visceral style and the war going on around him; however, Beethoven never gave up despite his despair and lack of encouragement. His courage to keep writing from the heart and his desire to play from the heart would eventually be accepted by the world. As a tribute to the soldiers, Beethoven was commissioned to write a symphony in honor of Wellington's victory over Napoleon. "The Wellington's Victory" was a favorite of the people of Vienna even though it was not one of Beethoven's favorites. Tragically, Beethoven's success could not be enjoyed. His health was fading quickly. In his last days, Beethoven finally wrote the symphony that touched his heart. The Ninth Symphony was his final work with the choral music put to Schiller's poem, "Ode to Joy." "Ode to Joy" spoke to the heart with words, and Beethoven's Ninth Symphony spoke to the heart with music. Sadly, Beethoven did not conduct his last piece of work because of his complete hearing loss. The applause was not heard by Beethoven; but the sight of the audience standing and continually applauding was Beethoven's acknowledgment of the appreciation felt by the Vienna people and the world.

Two bicycle repairmen embark on their dream to fly. With no formal training as either scientists or engineers, they study Lilienthal's diagrams for his glider and learn from experience the keys to controlled flight. As young boys, Wilbur and Orville Wright are full of ideas, enthusiasm and dreams. Above their bicycle repair shop they discover how birds are able to balance by tilting their wings - wing warping. They want to make a glider to do the same thing. "You have a dream, you should do it," their father encourages them. After writing to the "center of knowledge for flight'" Octave Chanute, they learn the best place to glide is Kitty Hawk, North Carolina. They tell Chanute about wing warping and make him promise not to tell anyone until they can perfect it. Their first attempts are unsuccessful, however, as they realize that Lilienthal's figures were incorrect. Wilbur and Orville begin experimenting with the figures. Meanwhile, others are beginning to take flight, but only in the beginning stages. Finally, Wilbur and Orville manage a controlled flight. All they need to do is add an engine. Chanute lets the wing-warping idea slip when he is challenged, but the Wright brothers are not worried - the rest of the world doesn't know how it works. After a 59 second flight, Wilbur and Orville take Santos-Durmont, the French flyer, up on his challenge to show the world they can fly in France and on August 8,1908 the Wright brothers demonstrate to the world the power of controlled flight.

When Helen Keller was a young child, she contracted a high fever that left her sightless and unable to hear. Being the parents of a non-seeing and non-hearing child was a hardship on two loving parents who did all they could but seemed to do it in the wrong way. Out of desperation, they hired a young educator, Anne Sullivan, to teach and train the young Helen. Much to the parent's dismay, Sullivan was a strict and firm disciplinarian with the young, spoiled Keller girl. Sullivan and Helen Keller moved into a house not far down the lane from the main Keller house. There they began to develop a trust and relationship of love and respect for each other. This soon turned into an atmosphere that was ripe for learning without the interference of the Keller parents. Once Helen Keller began to put meaning with the finger spelling that she was doing, she began to learn many words at a rapid rate. Her world began to open and she was able to complete her education and continue advanced training at the university.
