User blog:GuardDog216/'Failsafe' Logline?

Does anyone have a credible source for this apparent 'Failsafe' logline?

"The Justice League valiantly tries to defend against an alien invasion, but as the fierce invaders attack intensifies, the Team is called into action and forced to replace the Justice League after the heroes have fallen in battle."

Because the more I read it, the more it sounds like the summary for Season 2/Invasion rather than an episode. :\
