Shang-Chi is living a quiet life in San Francisco under the name Shaun, along with his best friend Katy, unaware that he is heir to a powerful and mystical legacy. His father, Wenwu, is the leader of the Ten Rings organization, an ancient group that has influenced historical events for centuries, wielding the mighty Ten Rings that grant longevity and great power. Having left his past behind, Shang-Chi is forced to confront it when his father's men unexpectedly come for him, thrusting him back into a world he thought he had left behind.

Reconnecting with his sister, Xialing, whom he had abandoned years earlier, Shang-Chi learns that his father is seeking a mythical village, believed to hold the secrets to immortality and untold power. He realizes that the safety of the village and the world is at stake if Wenwu finds it. Together with Katy and Xialing, Shang-Chi must come to terms with his heritage and his father's formidable legacy, embarking on a journey that will test his strength, his will, and his understanding of who he truly is.
