Can someone help me?

Hi everyone,
I'd like to write to my Florida friend about a movie that I have seen, but my English is not good and I need to brush it up.
I tried to write a summary of the plot but I m sure that there are a lot of mistakes in it.
Can someone explain me my mistakes and check out the text?
This is the text:
Ben was a barber who lived in London. He had a beautiful wife and a lovely daughter. The judge of the town covets her wife so he blames him for a crime that he did 't do and Ben was kicked out the town. After 15 years he cames back to London and discovered that the judge abused of her wife and became the tutor of his child. So he decided to revange of everyone that distroyed his life He looked for his barber shop where now there is a restaurant. He rented a room upstairs the restaurant and set up a new barber shop but instead of cut hair he cut his customs throat and under the seat there was a trap door in which he made fall down his victims. Then he sold the bodies to the restaurant downstairs that used them to make the meat pies. He was found out when a customs made a fuss because he found a finger in his pie.

I hope that someone can help me.
Thank a lot
