Frodo Baggins and the other members of the Fellowship continue on their sacred quest to destroy the One Ring--but on separate paths. Their destinies lie at two towers--Orthanc Tower in Isengard, where the corrupt wizard Saruman awaits, and Sauron's fortress at Barad-dur, deep within the dark lands of Mordor. Frodo and Sam are trekking to Mordor to destroy the One Ring of Power while Gimli, Legolas and Aragorn search for the orc-captured Merry and Pippin. All along, nefarious wizard Saruman awaits the Fellowship members at the Orthanc Tower in Isengard.
