About the movie "Room"

Today is August 31st. I would like to practice my English writing skill. I watched a Canadian-Irish movie yesterday, called “Room”. I will reveal some details of the movie below, so don’t read it this if you want to watch it. Also correct: "if you plan on watching it."
It is the story of Could also say: "The movie is about" a woman who was kidnapped and enclosed in a “room” seven years before the beginning of the plot. By this time, she had has had a child, who is 5 years old and is enclosed with her in the shelter.
As Also correct: "Because" her child is 5, she thinks he is big enough to understand there is a life outside of the walls and she decides to escape with him. She teaches him to fake death, so that the kidnapper (who also is is also his father) will take him outside of the room to buried him that he buried them in. She explains to her child that he will have to jump from the truck and that he has to give a note that she has written to anyone he will see in the street. A little less awkward: "...and that when he sees someone in the street, he has to give them a note she has written." The scene in the truck is very frightening. Fortunately, the plan succeed succeeds and the police also found present tense: find the woman thanks to the explanation of the boy.
The next part of the movie describes how they acclimate themselves to the world after all this those years captured locked up, imprisoned, in captivity (captured implies the action of being taken).
It is a very beautiful movie, extremely touching, showing the relationship between the mother and the child.
By the end of the movie, we can see than that the mother have has more difficulties than her child to return in in returning to the real life. But her child helps her with very simple children childlike words to go through this time and to continue living her life.
