Task: Question Answering
Input (English): Passage: The film begins in a parking lot in which a teenage filmmaker named Eric is attempting to document the faux-gangsta lifestyle enjoyed by Allison Lang and her boyfriend Toby's (Mike Vogel) gang of white upper-class teenagers living in the Pacific Palisades neighborhood. A brawl ensues between Toby's gang and another gang, which ends with both sides fleeing just before police arrive. Later that night, Toby's gang goes to a party at Eric's house, and Allison's relationship with Toby as well as her other friends Emily and Sam is further revealed. At the end of the party, Allison performs oral sex on her boyfriend.
The next day, Allison meets with her father, Stuart, at work to discuss family problems, the awkward conversation revealing the virtually non-existent relationship Allison has with her parents. Afterwards, she and her friends drive downtown into East LA, intent on buying marijuana, eventually encountering Mexican drug dealer Hector and his crew. Toby and Hector make a deal, but Toby believes that Hector did not sell him enough for what he paid, and attempts to confront Hector, who pulls a gun on him, humiliating him in front of his friends. Allison persuades Hector to leave Toby alone.
