Leonardo DiCaprio played Dom Cobb in this movie, he had this job where he would go into someone else's dream and recreated it. He would fall asleep in one dream and then he would be in another dream. It is one confusing movie.
It is rated PG-13 and they cuss a lot but that is just what PG-13 is. At the ending of the movie Dom Cobb goes back to LA and he ends up being with his kids. His wife has passed away and so he kept seeing his kids in his dreams and he always wanted to be back with his kids.
