Poe and BB-8 assign newly-appointed spy Kaz to the Colossus, a massive aircraft re-fueling platform on an outer rim water planet, home to colorful new aliens, droids and creatures. While undercover, Kaz works as a mechanic and lives with Poe's old friend Yeager, a veteran pilot who operates a starship repair shop run by his crew: Tam, Neeku and their old battered astromech droid, Bucket. Kaz soon finds himself in over his head with his new friend BB-8 as he'll have to compete in dangerous sky races, keep his mission a secret from his newfound family, and avoid the danger of the First Order.
