During a troop meeting, a robot messenger delivers Avani some exciting news: she has been invited to join a secret society of elite scouts known as the League of Lasers. She is eager to join their ranks, but first she has to survive her initiation challenge. Stranded on an uncharted planet, Avani must contend with the methane atmosphere, hostile frog-like inhabitants, and her dwindling supplies of food and water. But even worse: her arch nemesis, Pam, is stranded there, too.
