Synopsis:
Smallville plans a celebration of the hundredth anniversary of the Civil War. The re-enactment includes the Kent family, Lana Lang, and Lex Luthor. Superboy travels into space to stop an alien missile, but when he returns to Earth he sees Clark Kent participating in the play. Knowing that it can’t be the real Clark, he watches and thinks that the explosion sent him into the past where he is seeing the real Civil War.

The people involved resemble the future residents of Smallville, except Clark is a spy, and the Luthor duplicate is a hero. Superboy tries to alter history, but in each case he is thwarted by fate. Finally, he meets the Lana Lang duplicate who introduces him to two alien generals. The participants of the war are just android duplicates created by the generals. The explosion did not send Superboy into the past, but to another planet, where another re-enactment was taking place.
