The movie is based on the Marvel Comics superhero team the Avengers. It is set to be the direct sequel to 2018's 'Avengers: Infinity War', a sequel to 2012's 'Marvel's The Avengers' and 2015's 'Avengers: Age of Ultron', and the 22nd movie in the Marvel Cinematic Universe (MCU).
Following the events of Avengers: Infinity War, adrift in space with no food or water, Tony Stark sends a message to Pepper Potts as his oxygen supply starts to dwindle. Meanwhile, the remaining Avengers -- Thor, Black Widow, Captain America and Bruce Banner -- must figure out a way to bring back their vanquished allies for an epic showdown with Thanos -- the evil demigod who decimated the planet and the universe.
