Trini recounts her attempts to send distress signals from the desert. Lisa and Marc remind her that her messages had to reach somebody for a good response.
REHASHED FROM THE PREVIOUS FOUR EPISODES: At Shea Stadium, Marc observes the Mets' signals. He visits a researcher determining how bees communicate. In addition, Marc visits Bell Laboratories to see a computer that is programmed to speak (intermixed with portion of Human Voice animation from Episode 1). Lisa visits the (White Plains) New York School for the Deaf to learn sign language. Trini checks out a giant telescope in Puerto Rico intent on picking up sounds from the galaxy.
ANIMATIONS: Moths use pheromones; the history of communication.
