Barnum grew up poor and wasn't wealthy, on the other hand Charity was and her father forbidden her to leave and get married with Barnum. They took a leap of faith and left to start a new life in New York city. They had two lovely girls named Helen and Caroline.
Tight Rope
Barnum had the idea of opening his own attraction and he opened a wax figure museum. Didn't work out so he pursued his dream of opening his own circus. He went out and found the most extraordinary people for his show.
From Now On
Jenny Lind is a famous singer and Barnum happens to go to her show. He admires her singing and see's that he is perfect for his show.
This Is The Greatest Show
Charity misses Barnum and so does his kids. The fame and money got to him, and he even ended up forgetting his own family to be with Jenny. She even kissed him, it hurt Charity to see her husband left for work more because her kids where crying.
Everyone from the circus came back and explained how they felt. He promised to be better and reopened the show.
Barnum fixed everything and makes everyone happy. He then passes the duty of the circus to Phillpope and leaves the watch his girls grow up.
