As Langdon is showing off the cryptex, Silas appears and hits him over the head. Silas holds Sophie and Teabing at gunpoint and demands the keystone, but Teabing attacks Silas,hitting him on the thigh where his punishment belt is located,and Sophie finishes him off by kicking him in the face. They tie Silas up.
Collet arrives at the castle,but Sophie,Langdon,the bound Silas, Teabing, and his servant, Remy, escape and board Teabing's private plane to England. Sophie realizes that the writing on the cryptex is decipherable if viewed in a mirror.They come to understand the poem,which refers to "a headstone praised by Templars" and the "Atbash cipher," which will help them arrive at the password. Langdon remembers that the Knights Templar supposedly worshipped the god Baphomet,who is sometimes represented by a large stone head. The word,unscrambled by the Atbash Cipher,is Sofia.When they open the cryptex,however,they find only another cryptex, this one with a clue about a tomb where a knight was buried by a pope. They must find the orb that should have been on the knight's tomb.
Fache realizes that Teabing and the rest of them are in the jet. He calls the British police and asks them to surround the airfield,but Teabing tricks the police into believing that there is nobody inside the plane but himself. Then he goes with Sophie, Langdon, Remy, and Silas to the Temple Church in London, the burial site of knights that the Pope had killed.
Remy frees Silas and reveals that he,too,follows the Teacher. Silas goes to the church to get the keystone,but when he tries to force Langdon to give it up,Langdon threatens to break it.
