Here it is folks! The synopsis for season 4's finale! Lex Luthor is back! We knew that was going to happen but judging from the synopsis it is going to be an all out Luthor show down! Lex might have pulled off his plan to save The United States from an invasion ... an invasion from Kasnia that he helped plan! Lex is said to be at the White House this episode! He even has the power to summon his mother and sister to join him?! Very facsinating! Kara has one last chance to stop Lex's ultimate plan in what we believe will be a huge action-packed episode! Check out the synopsis below:
