Frodo Baggins and the Fellowship continue their quest to destroy the One Ring and stand against the evil of the dark lord Sauron. The Fellowship has divided; they now find themselves taking different paths to defeating Sauron and his allies. Their destinies now lie at two towers — Orthanc Tower in Isengard, where the corrupted wizard Saruman waits, and Sauron's fortress at Barad-dur, deep within the dark lands of Mordor. Based on the novel The Two Towers, the second in The Lord of the Rings trilogy by J.R.R. Tolkien.
