The story begins with the birth of Tristan. His mother, the princess of Cornwall, dies giving birth to him, and his father, King Rivalin of Lothian, is unable to raise his son due to his grief. Tristan is brought up by Gorvenal, a courtier who teaches him to hunt, fight, ride horses, and play the harp. By the time he is a teenager, Tristan is an accomplished and handsome prince.
When Tristan expresses a desire to see his mother’s homeland of Cornwall, his father the king agrees to give him a ship so he can travel there. Tristan leaves Lothian with Gorvenal and some of his other companions. When he arrives in Cornwall, Tristan goes to his uncle’s castle at Tintagel, forbidding his companions from telling anyone who they really are and where they are from.
Impressed by Tristan’s skill, King Mark employs him as a soldier. Tristan goes to war with Mark’s troops and singlehandedly defeats the Irish champion Morholt. He reveals his identity to King Mark, who promotes him to captain of the guards. However, a minor wound that Tristan received in his battle with Morholt quickly becomes life-threatening as Morholt carried a poisoned blade.
Wasting away from his wound, Tristan requests he be put adrift in a small boat so he can die on the open water. His boat comes ashore in Ireland, where he is found by Princess Iseult, a beautiful young woman who restores Tristan to health with her skills as a healer. Tristan is aware of Iseult watching over him but is too feverish to actually meet her. When he is well again, he returns to Cornwall to much celebration.
After his return, King Mark asks Tristan to help him find someone he can marry. The king sends him on a quest to find a suitable princess. Tristan travels across the British Isles before ending up in Ireland again. He learns that a dragon is terrorizing the land there, and the King has promised to wed his daughter to whoever can slay it. Tristan kills the dragon and Iseult once more heals his wounds.
Iseult briefly considers killing Tristan because he killed Morholt, but decides not to because he also slew the dragon. After competing in a tournament to further prove his worth to the Irish king, Tristan is allowed to marry Iseult. However, he says that she will marry King Mark instead to fulfill Tristan’s quest.
On the way back to Cornwall, Tristan and Iseult are forced ashore and stranded on a deserted beach for several days. Iseult tells Tristan that she is angry about the arrangement since she did not kill Tristan while he was wounded, in part, because she wanted to marry him. She is angry that she now has to marry King Mark instead. Tristan admits that he has feelings for Iseult as well. The two cement their love for each other before completing the journey to Cornwall.
Iseult marries King Mark shortly after returning to Cornwall. She and Tristan agree to keep their distance from each other to preserve both their reputations at court. However, they are now deeply in love and cannot stay away from each other for long. The king begins to suspect that they are still seeing each other, and so he follows Tristan one night to the place where he meets in secret with Iseult. At first, Iseult convinces the king that she is meeting with Tristan innocently, but when they are caught a second time, she is unable to deny they are having an affair.
King Mark banishes Tristan, who travels to Brittany to work for King Hoel. Hoel marries Tristan to his daughter, but Tristan never consummates the relationship because he still loves Iseult.
While on a quest with Hoel’s son Kahedin, Tristan is injured and sends for Iseult to heal him. If Iseult agrees to come, Tristan instructs the ship traveling to Brittany to fly white sails and to fly black sails if she refuses to come. Iseult hurries to help Tristan, but Tristan’s new wife, out of jealousy, lies to her husband, saying that the approaching ship is flying black sails.
Tristan dies of grief, and Iseult, who arrives soon afterward, dies beside him. They are returned to Cornwall where they are buried together with a hazel tree growing from Tristan’s grave and honeysuckle growing from Iseult’s.
