Danny Rend is a smart, strong and brave guy whose life has been extremely difficult since early childhood. He was born into a wonderful family, where parents were looking forward to the appearance of a long-awaited child and were happy to raise him. They wanted to show their son the world, but another journey through the Himalayas turned into a real tragedy. The weather conditions on vacation changed a lot, and a powerful storm claimed the lives of many tourists, including the parents of little Danny. By the will of fate, he managed to survive and get to the ancient city called K'un-L'un, where he found a new home.
For many years he remained in this place, learning martial arts and ancient techniques that were known only to true masters. He was distinguished by amazing strength, because he lived for revenge and dreamed of one day understanding the death of his parents, because on that terrible day there were still people nearby who wanted Daniel's family to die. Being the best student of his mentor, he got a chance to fight against a powerful dragon and achieve the power of the Iron Fist. He managed to cope with all the trials and emerged victorious. Now he has a unique power and is ready to return to his native New York to save him from rampant crime.
