Epiphanies in the Shower!

I have found that showers are the best places for epiphanies!! I've been working out some ideas for writing my play, and the other night in the shower, I came up with an idea for the premise of my play! It will be about a girl of about 16, named Elizabeth, who lives in a city with her mother during WWII (or some war). Her father is off at the war. Her mother is a skilled nurse, so sick people often come to their house. One night a man comes to their place with a mysterious illness. Several days later, the Elizabeth's mother falls ill as well. Lissie tries to nurse her mother to the best of her ability, but unfortunately, she fails. She tries to send word to her father at the front, but soon receives the news that her father is missing in action. She is sent off to an orphanage, where various trials and tribulations ensue. She must work in a way she never has before, and it is very difficult for her to adjust to her new life. However, she is persevering, and she is able to escape the orphanage and become a governess, for she always loved school and teaching. She stays with a family that lives in a large estate in the countryside, and the family soon begins to take in wounded soldiers. After Elizabeth has been with the family for several months, a man arrives from the front who was wounded and consequently had amnesia. However, he is beginning to regain it upon his arrival at the convalescent home. Can you guess who it is? You got it! It's Elizabeth's father who had gone missing!! Cue a joyous family reunion! :) Now comes the hard part...actually writing the script!
