Shunned by the people he has sworn to protect, Robin is taken to Nottingham Castle by Gisborne. But Tuck, convinced that Robin is not to blame, attempts a daring rescue mission to clear the outlaw's name and convince him to take up his bow once more. For how else will free men rally to the legend of Robin Hood?
