She doesn't mind quietly doing her homework and begin prep for college. High school hasn't been her favorite fun time and she can't wait for summer to roll around again. For her friends and Brad, her boyfriend, however, they really want to leave the school with a bang. They want to be a legendary senior class and they want to go down in history for all the classes after them. Brad comes up with an elaborate plan to take over the school and teachers disguised as the annual senior prank. Roxie knows it's a bad idea. She knows it'll get out of hand. Her friends shun her when she decides to take no part in the take over. None of the teachers believe her when she tries to warn them and she has the whole school against her. Some say senior year is the best. For Roxie, it's going to be a long one.
