The narrative follows a sequence of chivalric episodes centered on Sir Tristram and other knights of the Round Table. It recounts tournaments, rescues, and revenge duels, including Tristram's clashes with King Arthur and his rescue of Sir Palomides, which leads to arranged combats; the arrival of Tristram at court escorted by Sir Launcelot; quarrels involving King Mark, Lamorak, Dinadan, and Palomides; and the elevation of Percival to knighthood after a mute maid speaks. Recurring themes include martial honor, tangled loyalties, romantic jealousy, and the fragile code that governs knightly reputation amid betrayal and grief.
