This is a Firefly/Academy crossover that takes place six years after the events from the movie, "Serenity". The people now know the lengths the Alliance will go to in order to keep power, and the civil unrest that is more common to the boarder planets is being seen in the core. Freedom fighters rally under the Browncoats banner, and elite teams train in the ultra-secretive, and ever illusive Academy. Captains Malcom Reynolds and Zoë Washburn head the resistance, while the Tams (River, Simon, and his new wife Kayli) run the Academy, and Jayne and the companion Inara are regular liaisons between the two.
This is the story of one of those elite teams, handpicked by the Captain himself to crew his firefly class transport ship, Serenity. In a cover run where the Blackbourne crew are smuggling medicine and supplies out of Ariel, they take on a small group of passengers...but not all who board are what they appear to be...
