Inception

The main character of the inception movie is Dom Cobb (Leonardo Dicaprio). He is a thief who is very demanded in he espionnage business because him and his team specialize in a very specific domain called extraction. He sneek into the dreams of other people while they're asleep, and steals ideas, thoughts, and secrets from their mind. The fact that not many people are known worldwide to be experts in this field gives Cobb a lot of success. However, his work also causes him to become an international fugitive, and he has to abandon all the things that he cherishes the most because of that. Therefore, Cobb is forced to live a very lonely life, but a unique job offer that is given to him once gives him the opportunity to change his fugitive life back to normal. Instead of stealing thoughts from the mind of a person, he has to plant one, and if he succeeds, he'll have a chance to turn his life back to normal. This process that Cobb is asked to complete, which is basically the opposite of extraction, is called inception, and has never been done before by any specialist whatsoever.
