A quirk of evolution has given humanity a different reproductive cycle. People can either remain at the larval stage, or submit themselves to a precarious transformation and become adult. Two larvals find their friendship put to the test when Megan's curiosity about adulthood threatens to separate her from Sal. They must navigate this unfamiliar morality and an all too human bureaucracy. A detective, Augustine, charged with monitoring the wanton destruction of eggs, decides to mentor them. Now his mastery of maturity will be put to the test.
