Scott Pilgrim vs. the World

In Toronto, Scott Pilgrim, played by Michael Cera, dates Knives Chau, a 17-year-old high-school student, to the disapproval of his friends in the band, his younger sister Stacey, and his roommate Wallace Wells. Scott meets Ramona Flowers, an American Amazon delivery girl, at Julie Powers’ party, after having first seen her in a dream. Scott loses interest in Knives but does not break up with her immediately before pursuing Ramona. When Sex Bob-Omb plays in a battle of the bands sponsored by record executive Gideon Graves, Scott is attacked by Ramona's ex-boyfriend Matthew Patel. Scott defeats him and learns he must defeat Ramona’s remaining six evil exes in order to date her.
