Picking up where The Avengers (2012) left off, Age of Ultron follows the team as they face a new threat. Nick Fury (Samuel L. Jackson) enlists the help of Tony Stark/Iron Man (Robert Downey Jr.) and Bruce Banner/Hulk (Mark Ruffalo) to create an artificial intelligence system, codenamed Ultron. The goal is to protect the world from external threats, but things quickly spiral out of control.
