The following is a polished version that enhances the emotional tension and the delicateness of character portrayal: --- When he first entered the iron window, Malik El Jaben (Tahel Rahim) is a lonely and helpless young man.He was only nineteen years old and could not even write his own name.The six-year sentence was like a cold wall, completely isolated him from the outside world.When he first stepped into prison, he looked cowardly and had a thin body, as if a gust of wind could blow him down. Among these fierce and cold prisoners, he was like a lamb who had accidentally entered the pack of wolves.Soon, he was controlled by a powerful Corsica gang and became a pawn in their hands at the mercy of others.However, it was in the "tasks" that Malik gradually faded away his immaturity and fragility.He learned to observe in silence and to survive between violence and betrayal.His eyes became firm and his movements became more decisive. Finally, he won the trust of the Corsica group that once looked down on him - and quietly embarked on the road of no return from prey to hunter. --- If you need to further adjust the tone according to the style of the film or the purpose of the promotion (such as more literary, commercial or more suspenseful), you are welcome to continue to provide direction.
