Ada Lovelace is not your average 19 year old girl growing up in the 19th century. She's a programmer, a mechanic, an enchantress of numbers. While interning for the great Charles Babbage she finds that there is more to the Difference Engine than sequences and algorithms. It is the brain of the clockwork pacemaker, driven by steam and the genius of a man bent on saving his son's life. Henry Babbage is only 8 years old and in the world he may never grow up in, there are no medicinal cures available for his terrible condition. His heart is about to give out. Ada takes the challenge and commits herself to solving the secret of the Difference Engine to save a life and create the first Pacemaker.
