Tamina manages to slip into the mountain where she must pierce the rock with the Dagger, killing herself and sealing the Dagger away forever. They are ambushed by Dastan's brother but are forced to fight together when the Hassansins attack again. He does not return her the Dagger but goes with her. They reach the sanctuary where Tamina asks Dastan for the Dagger so she can return it to the mountain since she is the guardian of the Dagger. Before they get there, they are captured by the Sheik once more and have an encounter with the Hassansins. Dastan later catches up with Tamina who is travelling through the desert to the Dagger's sanctuary in India. The Dagger is gone and Nizam arranged for Dastan to be killed, but failed. They finally make it back to the royal city where Dastan gets Nizam, the King's brother, alone with him to show him the Dagger and it's powers. After Dastan is caught and the Dagger is taken, she frees the Ostriches and the weapons cache, allowing Dastan to regain control of the Dagger and the both of them to escape. She then is taken and made to serve water in the ostrich racing the Sheik has set up along the roads. He denies it but she mentions how he can never take his eyes off of her. They all travel back to the city where she mentions that Dastan is always leaping to assist her. Later, she is seen trying to pour sand hidden in a jewel around her neck into the dagger but is stopped by the Sheik and Dastan who sold her into slavery. She feigns death and knocks Dastan out with a large bone.

They go through the Valley of Slaves in an attempt to get to the King's funeral. She refuses to answer him when asked if there was more sand, by saying there was no more of this sand. He reverses time once more and stops the fight prematurely, showing her how he knew it could reverse time. She once again is caught trying to steal the dagger but manages to wound Dastan with her sword. Dastan notices and they fight with one another until he accidentally presses the jewel hilt and reverses time to when she was trying to seduce him.

Along the way, Dastan and Tamina make camp where she tries to seduce him into kissing her, thereby giving her a chance to steal the dagger. When Sharaman is killed by a poisoned robe given to Dastan by Tus from Nizam, Tamina helps Dastan escape after he is accused of murdering the King. She is later presented to the King of Persia. At first she refuses, but after noticing Dastan with the Dagger, she accepts. As the soldiers invade the chamber, she is captured and offered to be married to Tus. However the Dagger fell into the hands of Prince Dastan who took it thinking it is an ordinary knife. As the Persian invaded the city, she entrusted the Dagger to Asoka, one of her soldiers to make sure it would be kept safe. When the Persians attacked her holy city of Alamut, princess Tamina went to the high temple to pray and retrieve the Dagger of Time. Tamina is a Hindu, as the Gods of Alamut are Hindu deities and the mythology and idols referenced and seen throughout the film are of Indian origin. She was taught that it was her sacred calling, her destiny to protect the dagger no matter the consequences, even if it required her death. It was her duty and that of Alamut's royal family to protect this and the Sandglass of the Gods. She was trained to become a capable fighter but most of all, she was trained to protect the powerful relic, the Dagger of Time.

As a young girl, princess Tamina was trained to become a guardian as all of her ancestors did before her.
