Rogue One

Rogue One was the callsign given to the squad of Rebel soldiers that took it upon themselves to steal the plans to the Death Star, an armored battle station that was being constructed by the Galactic Empire. Though the squad succeeded in its mission, none of the team survived; those who didn't die in battle during their attempt to steal the plans perished when the Empire destroyed the base on Scarif with the Death Star's superlaser.[1]
