Ideas for Musical

My idea of the plot (Main story) for the musical Cell Block 33 is about two girls. The two girls are called Carla and Nicole who are half-sisters/ sisters and Carla was abused by her step father when she was little. Now they are both older, Carla decides to tell the police but can’t prove it, so instead she asks Nicole to help her beat him up for revenge. She promise to Nicole that there just going to beat him up and nothing else but she lies and stab him instead. The step father survive the attack so Carla gets 8 years in prison for attempted murder and Nicole gets arrested for assist attempted murder.

They don’t speak to each other that much ever since they were sent to prison but Carla then become popular prison and turn everyone against her. Nicole then gets a new cell mate and tries to get Carla and Nicole friends again.
