D&D have to fight a hired chinese assassin ninja: Bruce Lee Harvey Oswald (played by Jackie Chan in his first american role).
Saving Lincoln Dutch and DIllon return to modern america but now find that the Blacks are in charge and whites are slaves. Now its Dillon's turn to boss around Dutch!!. Turns out after the civil war Lincoln passed a law taking away all the rights of whites, to teach them a lesson.
