But when a tragic turn of events gives Dennis a 30-day death sentence, he discovers his accident comes with super-powers. And as the weeks in Dennis' life tick down, he sets out to leave a mark one way or the other - even if he has to go through Spider-Man, the Fantastic Four and the Avengers to do it.
