The opening scene of Inception shows the main protagonist washing ashore on a beach in a confused and exhausted state. As he lies on the beach, he hallucinates seeing two children playing, creating confusion for the audience about his mental state. He is then seen with a gun to his back by a man in a military uniform, establishing tension. The introduction also shows an old man closely examining a small trinket, implying it will have significance later in the film and setting up a sense of mystery.
