When william wallace was a child, his father, the Scottish hero Marcelo Wallace, died in the struggle with the British. He studied culture and martial arts under the guidance of his father's good friends in his early years. Time flies. In order to consolidate his rule in Scotland, King Edward of England issued a decree to allow British nobles to enjoy their first wedding night in Scotland, so as to make them loyal to the royal family. Isabella, the princess of the prince, is a decisive talented woman. She knew that this law would make the British nobles interested in Scotland, but it would also arouse the resistance of the Scottish people. Young Wallace returned to his hometown and proposed to the beautiful girl Miron, willing to be a contented person. However, Melen was robbed and killed by the British for no reason, and Wallace finally broke out. With the villagers shouting "Hero Queen", they rose up, killed British soldiers and declared an uprising.

Robert, a Scottish aristocrat, wanted to become a Scottish Lord, and at the instigation of his father Booth, he formed a false alliance with Wallace. Wallace defeated the attacking British army, and the Scottish Parliament made him a knight and appointed him lord protector of Scotland. Wallace found that these Scottish nobles only considered their own interests and did not worry about the future of the people and the country at all. Edward sent Isabella to the peace talks to ease the situation. But the peace talks failed, because the British king didn't consider the freedom and equality of the people at all, and only wanted to buy Wallace as a condition. Isabella came back and realized that the peace talks were just a cover. The king joined the Irish army and the French army together with the Scottish army that surrounded Wallace. She quickly sent a letter to Wallace. Under the pressure of the army, the nobles were in a panic, and Wallace led the troops into battle. In a melee, he accidentally found Robert colluding with the king of England, and he couldn't help being hit hard. Isabella fell for Wallace's lofty sentiments and came to the station to pour out her true feelings to him. They are intoxicated with the happiness of love. The king of England once again proposed peace talks. Wallace knew it was a trap, but he agreed to go for peace. In Edinburgh, Booth devised a plot to capture Wallace and hand him over to the king of England. Rob was furious with his father's tricks, and Wallace was finally sentenced to death. Isabella failed to intercede. Before the king died, she told him that she was not pregnant with the prince's blood and that the child would soon become the new king.

Wallace shocked everyone by shouting "freedom" before the execution. When he was blocked a few weeks later, Rob shouted the slogan of revenge for Wallace and bravely inherited Wallace's legacy of resisting the British.
