Summary:
March 1876: Alexander Graham Bell struggles with an invention that may change the world. Early nineteenth century America is experiencing an explosive growth and expansion across a vast landscape. A technology is needed to meet the communication needs for this new nation, and Bell is convinced that he can transmit speech over great distances. Early telegraphs can only transmit one message over one wire at one time, and the message must be coded and decoded one letter at a time. Bell begins work on a multiple telegraph, but his genius will lead to a different revolutionary device that will carry thousands of simultaneous messages and shape the future--the telephone.
