Zain is a young man who flees his hometown after a theft attempt, only to find himself drawn into a dark cave by fate. Inside the cave, he encounters a princess from the realm of the jinn who guides him into the labyrinthine darkness to fulfill a prophecy. He eventually falls into a river and wakes up in a strange, lush land filled with mountains, forests, and plains.

There, he battles and defeats the fiercest of beasts, though he is injured in the process. A family from a foreign tribe takes him in, believing him to be the prophesied one they've been waiting for. Zain is introduced to the world of the Jinn princess and meets her father, the ruler. He embarks on an adventure to uncover the source of the evil threatening the land, entering the corpse of a wild animal to be carried by a giant predatory bird to confront the menace.

Facing this threat, Zain decides to stand against it with the help of the jinn and other tribes. Uniting their forces, they defeat the evil in a fierce battle, during which Zain wields a sword gifted to him by the jinn ruler. Three warrior knights appear whenever he uses the sword, aiding him in fighting the evil or the monsters sent to kill him.
