Meanwhile, Frodo Baggins and Samwise Gamgee are led by Gollum to Minas Morgul where they witness the Witch-king of Angmar leading an Orc army to drive Denethor's younger son Faramir and his men from Osgiliath. At Gollum's urging, the three begin climbing a precarious stair carved in the cliff face that will take them into Mordor via a 'secret way'. But having overheard Gollum's plot to regain the Ring, Sam keeps a suspicious eye on him. In Gondor, Pippin follows Gandalf's instructions and secretly lights the beacon to signal Théoden to assemble the Rohirrim and come to Gondor's aid.
