At the beginning of the story Scrooge's worker was shivering and he didn't do anything about it because he is frugal. He hates Christmas and refused to give in and was very selfish. He never did anything for Christmas and was very against the holiday. Whenever someone asked him to join them for Christmas he would scream things like "BAH,HUMBUG". In the video
Then that night he got a visit from his old partner, Jacob Marley, who has died. His partner came to warn him about the three ghost that are coming to visit him that night. Scrooge went to sleep and got woken by The Ghost of Christmas Past, The Ghost of Christmas Present, and The Ghost of Christmas Future. These three ghost showed him memories, generosity and his fear of death.
The ghosts made Scrooge change for the better, Scrooge became a more generous man and loved Christmas more. His new found Christmas spirit causes him to join and help with the Christmas event he was invited too. The video showed that after the ghosts visited he woke up more joyful and was talking to people on the streets
