Iron Man 3

Plagued with worry and insomnia since saving New York from destruction, Tony Stark, now, is more dependent on the suits that give him his Iron Man persona—so much so that every aspect of his life is affected, including his relationship with Pepper. After a malevolent enemy known as the Mandarin reduces his personal world to rubble, Tony must rely solely on instinct and ingenuity to avenge his losses and protect the people he loves, as he begins an odyssey of rebuilding and retribution.
