This animated adventure finds the ultimate superhero Superman succumbing to the clutches of disturbed criminal mastermind Lex Luthor, who has constructed a plan to murder the Man of Steel with solar radiation. Following his exposure to the deadly phenomenon, Superman is sure he only has weeks to live, and lays plans to make good on the many tasks that ahead of him before he expires -- including telling the truth about his secret identity to Lois Lane, and defeating Lex once and for all. But is the hero's fate truly sealed, or can he appeal the fatal sentence and live to fight once more?
