Indy has the third piece of the famed Philosophers' Stone in his grip -- but only for a moment and then it vanishes, first by the hand of the Russian military and then through agents of the mysterious Nazi Jäger. Indy has been warned that the stone, once re-formed, can tip the balance of life and death and be used for hideous and evil purposes. Now he's in a race with the Russian Comrade Major Nadia Kirov to win back the third piece, on a one-way train, straight into the mouth of the enemy!
