Meet Stuart Zissu, a 12-year-old Rebel, and 4B-X, a super-smart droid who can answer almost every scientific question. They join the famous droids R2-D2 and C-3PO on a top secret mission for the Rebellion. After stormtroopers attack their ship, Stuart and the droids must use 4B-X's scientific knowledge in order to pilot and land their runaway escape pod--or else.
