In 1286, King Edward "Longshanks" invades and conquers Scotland following the death of Alexander III of Scotland, who left no heir to the throne. Young William Wallace witnesses Longshanks' treachery, survives the deaths of his father and brother, and is taken abroad on a pilgrimage throughout Europe by his paternal Uncle Argyle, where he is educated. Years later, Longshanks grants his noblemen land and privileges in Scotland, including Prima Nocte. Meanwhile, a grown Wallace returns to Scotland and falls in love with his childhood friend Murron MacClannough, and the two marry in secret. Wallace rescues Murron from being raped by English soldiers, but as she fights off their second attempt, Murron is captured and publicly executed. In retribution, Wallace leads his clan to slaughter the English garrison in his hometown and send the occupying garrison at Lanark back to England.
