Inception is a 2010 sci-fi thriller directed by Christopher Nolan. The film follows Cobb, a professional thief who specializes in stealing information from people's subconscious during dreams. Cobb is offered a chance to return home if he can successfully perform "inception," or planting an idea in someone's subconscious, which is believed to be impossible. The target audience is teenagers and adults, as some scenes may not be suitable for younger viewers. The film follows a typical three-act structure as Cobb and his team work to complete their mission, encountering obstacles along the way. At the end, it is left ambiguous as to whether Cobb has truly returned home or is still dreaming.
