It's actually the exact opposite. We are not on a hero's mission, we are new recruits to the Resistance who are being evacuated from the Batuu base due to Finn's undercover team aboard Kylo Ren's Star Destroyer informing us that the First Order are on their way. We are being taken to the new base by General Beck and are captured before we can leave the system, while Poe, being the only surviving escort, escapes to bring reinforcements. Once aboard the Star Destroyer and in the prison cell Finn's Resistance team breaks us out of the cell and provides us with transports to take us to the escape pods. Mayhem ensues and we finally escape after being pursued by Kylo Ren who is after us because we know the location of the new Resistance base.
