Mary Anne has never been a leader of the BSC. So when a fight breaks out among the club's four members, Mary Anne feels a little lost, unable to depend on Kristy, Stacey or Claudia anymore. Sitting by herself in the cafeteria is bad enough; when Mary Anne has to babysit a sick child without any help from the club, she knows someone has to take action. It's time for Mary Anne to step in and save the day!
