Richard the Lionheart, King of England, is taken captive in 1191 by Leopold V, Duke of Austria while returning from the Holy Land. Richard's treacherous brother Prince John usurps the throne and proceeds to oppress the Saxons, raising taxes to secure his own position.
Only the Saxon nobleman Sir Robin of Locksley opposes him. Robin acquires a loyal follower when he saves Much the Miller's Son from being arrested for poaching by Sir Guy of Gisbourne. At Gisbourne's castle, Robin boldly tells Prince John and his Norman followers, and the contemptuous Lady Marian Fitzwalter, that he will do all in his power to restore Richard to the throne. Robin escapes, despite attempts by John's men to stop him.
Robin, Much, and friend Will Scarlet take refuge in Sherwood Forest and recruit Little John, while other men join their growing band, including the rotund Friar Tuck, an accomplished English swordsman.
Branded as outlaws, Robin binds his men by an oath: to fight for a free England until the return of Richard, to rob the rich and give to the poor, and treat all women with courtesy, "rich or poor, Norman or Saxon". Robin and his band begin a guerrilla war against Prince John, systematically killing the Prince's tax collectors and any Norman nobleman or man-at-arms who abuses his power.
Robin and his men capture a large party of Normans transporting tax money extorted from the Saxons. Among Robin's "guests" are Sir Guy of Gisbourne, the cowardly Sheriff of Nottingham, and the Lady Marian. Disdainful of Robin at first, Marian comes to accept his good intentions and to see the reality of Norman brutality. Robin allows the humiliated Sir Guy and the Sheriff to leave Sherwood, telling them that they have Lady Marian's presence to thank for their being spared.
