The Lord of the Rings
Samwise comes to the Tower of Cirith Ungol, but the different Orc groups in it had a fight and almost all of them are now dead. Sam frees Frodo and gives him back the One Ring. The two hobbits disguise themselves as orcs, escape from the Tower and continue their journey through Mordor. It is a hard journey, and the Ring's influence on Frodo is very strong now. One time the hobbits are forced to walk with an army of orcs, but they can escape without being discovered.
