LOTR
Frodo and Sam are able to catch a couple of lone orcs off guard. They take their armor and pass through the Black Gate under the guise of orcs. Once inside Mordor, they manage to get away from the army of orcs during the night. They continue their journey towards Mount Doom. The army of men and elves, led by Aragorn, pull the army of Mordor to the Black Gate, allowing Frodo and Sam to successfully reach Mount Doom. However, once they get there, Frodo cannot destroy the Ring. When he puts the Ring on, the Nazgul find him, take the Ring, and return it to Sauron. Despite how close they were to success, the Ring once again wins out and Middle Earth is doomed.
