Description from Star Wars databank.

FINN

Committed to the cause of the Resistance, Finn fights alongside his closest friends in the struggle to defeat the First Order, the evil regime he once served as a stormtrooper. As FN-2187, he was trained from birth to serve the First Order, but a skirmish on Jakku awakened his conscience and drove him down a different path, one that proved both heroic and dangerous.
