Helena asks for her subprefecture's secretary to help her clean up the local beaches. The reason is that, a few days earlier, she went to the beach with her friends and polluted the environment with packaging (including glass bottles). Arriving home, she was so remorseful that she even dreamed of the consequences. The following day, she returns to the beach and finds a commotion around the bloody remains of an accident in which a child hurt himself by stepping on the glass bottle that she littered the beach with on the previous day.
