As they left Biff accidentally knocked into Sarah McMillan. She was really annoyed now. First they wouldn't shut up and now they had bumped into her. She was glad that they were leaving so she could finally enjoy the movie.
Once the movie had ended Sarah left the theatre and was just wondering what to do next when a security guard approached her.
"Excuse me young lady" the man said. "Where are your parents?"
"They're at home" Sarah replied.
"Uh huh" the man replied. "Are you with anyone else? A brother or uncle perhaps?" Sarah shook her head. The man frowned. "Right come with me" He took Sarah's hand and started leading her somewhere.
