Okay, so now I'm going to start going over the characters a little more in depth:

Annie:

I already went over Annie quite a bit, but I'll just give a short description of the show; 

In the depths of the 1930's, Annie is a 

fiery young orphan girl who must live in a miserable 

orphanage run by the tyrannical Miss Hannigan. Her 

seemingly hopeless situation changes dramatically when she 

is selected to spend a short time at the residence of the 

wealthy munitions industrialist, Oliver Warbucks. Quickly, 

she charms the hearts of the household staff and even the 

seemingly cold-hearted Warbucks cannot help but learn to 

love this wonderful girl. He decides to help Annie find her 

long lost parents by offering a reward if they would come to 

him and prove their identity. However, Miss Hannigan, her 

evil brother, Rooster, and a female accomplice, plan to 

impersonate those people to get the reward for themselves 

which put Annie in great danger. SPOILER PART BEGINS: 

They (obviously) don't succeed, and Annie parents had 

actually died in a car accident after giving her up for 

adoption, but Annie ends up with Warbucks (who marries 

Grace!). After they get married, they decided to adopt all the 

orphans from Annie's orphanage.
