"Inception" is a 2010 science fiction film directed by Christopher Nolan and starring Leonardo DiCaprio as the main character, Cobb. The film follows a group of thieves who specialize in entering people's dreams and stealing their secrets.
Cobb is recruited by a wealthy businessman named Saito (Ken Watanabe) to perform a rare and potentially impossible feat: planting an idea in someone's mind rather than extracting one. To do this, Cobb and his team must journey into the depths of the dream world and navigate a series of increasingly complex and dangerous dream levels. Along the way, they must also confront their own personal demons and the consequences of their past actions.
"Inception" is known for its impressive visual effects, mind-bending plot, and strong performances by the cast. It was a critical and commercial success and has since become a modern classic of science fiction cinema.
