Peter Quail (Chris Pratt) is an Earthman who was kidnapped into outer space since he was a child. Under the cultivation of his father Yongdu (Michael Rooker), he became the ultimate gangster, calling himself the "Star Lord". During an operation, he stole a mysterious sphere and became the kidnapping target of bounty hunters Rocket Raccoon (voiced by Bradley Cooper) and tree man Groot (voiced by Van Diesel). The mysterious Gamora (played by Zoe Saldana) is also determined to get the mysterious sphere. After a bumpy encounter full of jokes, the Star-Lord is forced to form a small team with the three men and the vengeful "Destroyer" Drax (Dave Batista) to escape the pursuit of "Accuser" Ronan (Lee Pace). However, this mysterious sphere has infinite power, and the team must unite to deal with Ronan in order to save the entire galaxy. This was how the Guardians of the Galaxy were born.
