Well... mostly after the father married the evil stepmother, she murdered him for his cash, and then used his daughter as the slave of the house and spoiled her own two daughters with the cash. They practically starved the daughter and everyday after she was done with her work, all she had for warmth were the cinders left in the fire place, which is where she got the nickname 'Cinderella' because she'd sleep next to the cinders. If she didn't do something fast enough, she'd be whipped, just like a slave. Sometimes to earn extra money, because 'they could never have enough', the stepmother would rent out her daughter much like a prostitute. She was unwilling so she'd often come back scarred up as a rape victim, but of course no one took pity on her.
One day the prince held a ball and invited all the maidens in the city, except Cinderella, because the stepmother made sure no one knew she existed. Cinderella was forced to prepare her stepsisters for the ball, and if she did something wrong (like mess up their hair, slightly smudge their makeup, tie something too tight, etc.) then she'd be whipped and slapped. Eventually after the two stepsisters left for the ball and the mother left with them, Cinderella was finally alone in the house and currently did not have to do chores if she didn't want to, so she just sat down and cried from all the pain her life caused her. The ghost of her father showed up from her tears and sat beside her, along with the ghost of her birth mother as well who had died while she was very young. Together, the spirits magically sewed together a beautiful gown for Cinderella and they healed all her scars and put makeup on her to cover her bruises and she looked absolutely beautiful. The spirits turned a pumpkin into a wondrous coach and some mice into horses and they sent her off to the ball, warning her that the magic would wear off at midnight.
At the ball, everyone thought she looked absolutely stunning. But off course, since no one knew Cinderella existed, no one knew who she was. Her beauty even stunned the stepsisters and step mother and they didn't recognize her. Everyone thought she was a princess from some other kingdom. The prince was mesmerized and asked her to dance with him and they fell in love. However, the clock began to chime midnight and she quickly ran off with only a small goodbye to the prince, telling him he would never see her again. As she ran down to her enchanted coach, one of her glass slippers fell off and she tripped, but she quickly regained her footing and scrambled into the coach, which immediately set off. The prince ran down after her with her slipper which he picked up and tried to call her back so he could return it to her, but she'd vanished out of sight.
Once the stepsisters and stepmother returned home and they saw Cinderella in her rags sitting on the floor, she was violently beaten for not doing her chores.
Over the next few months the prince traveled the kingdom and even out to other lands to try to find Cinderella, saying whoever's foot fit the slipper she left would be his princess. But like I said before, no one knew she existed, and when he described her, no one could tell him where she lived or who she was. He stopped by her house once, as well, but the stepmother had locked her away in her room. The stepsisters tried to fit their giant feet in the slipper but it was impossible.
After a while the prince had even put out a reward for whoever could name his princess, and of course the stepmother was enthusiastic about money, so she planned to bring Cinderella to him and collect the money, but then she would murder her afterwards and say she'd had a terrible disease that the stepsisters also shared, and they were very poor and if they had enough money to afford medicine then her two other daughters could be saved, so she would collect donations from the kingdom for more money.
However, after Cinderella married the prince she told him about her stepmother's plan and she was caught in the act. She was later hung for murdering the father and for attempted murder of Cinderella. The two stepsisters were banned from the kingdom for torturing Cinderella.
And I suppose right here you could say she and the prince 'lived happily ever after' once all the death and money was out of the way.
But it's a story that endures several versions so that might not be the exact story. It's just what I remember.
