The eternal search for a job brings Firefly's team to the planet Canterbury. But the deal seems suspicious to Mel, and he decides to refuse. However, Jane Cobb's greed overpowers, and the thug secretly smuggles a trunk with an unknown apparatus aboard the Serenity. From that moment on, the entire team begins to hallucinate about the life that they could have had, about unfulfilled dreams and hopes. It would seem that there is nothing wrong with dreams, only the action of the “illusion machine” has a deadly side effect.
