While continuing the style of the first part, the second part presents a multi-line development pattern, and the plot has a higher ornamental value. At the end of the first part, after Boromir was killed by the Uruk-Octoks, the two Hobbits Pippin and Merry were also kidnapped by the Uruk-Octoks. Aragorn, the elf Legolas (Orlando Bloom), and the dwarf Gimli tracked the Uruk-Octoks all the way to rescue Pippin and Merry, and met the "resurrected" white-robed wizard Gandalf (Ian McKellen). At this time, the white-robed wizard Saruman, who surrendered to Sauron, controlled the king of the human kingdom of Rohan and sent a large number of Uruk-Octoks to prepare to destroy humans. Under the leadership of Gandalf, Aragorn, Legolas and Gimli helped the kingdom of Rohan fight against the invasion of evil forces.

Under Gandalf's instruction, the tree spirits protected the safety of the two and took them to the tree spirit conference. At the conference, the tree spirits discussed their attitude towards the Middle-earth War: should they continue to be neutral, accept the fate, or rise up to resist? Frodo (Elijah Wood) and Sam, who were burdened with heavy responsibilities, continued to move forward to Mount Doom. They were followed by Gollum along the way. Frodo relied on the power of the One Ring and became Gollum's master. Under Gollum's leadership, they arrived at the entrance of Mount Doom, the Black Gate. Just as they were about to enter, Boromir's brother Falmer appeared and took them back to Gondor. Frodo encountered a new crisis: Falmer wanted to use the power of the One Ring to fight against Saruman's attack...
