I agree it should TOTALLY be an epic series:
Nundercover
Jason has already written this one by now, so we don't need a tagline.
Nundercover 2: Nunderdome
The Nun has to go Nundercover as a sexy biker chick to expose a ring of illegal bike jousters.
Nundercover 3: Nunderwater
The Nun has to go Nundercover yet again as a sexy deep sea diver to expose a ring of human traffickers.
Nundercover 4: Nunderwhelmed
The Nun has to go Nundercover as a sexy kindergarten teacher at a failing inner city school to expose a ring of drug dealers. HAS NOTHING TO DO WITH SISTER ACT 3.
Nundercover 5: A True Nunderdog Story
The Nun has to go Nundercover as a sexy showdog trainer to expose a ring of dogbreeders who have been genetically engineering dogs by splicing their DNA with other, cute animals. The Nun dies at the end, like Marley and Me.
Nundercover 6: Rise of the Nundead
The Nun, rising from the dead, has to go Nundercover as a sexy UN Weapons Inspector to expose a ring of scientists who are harvesting organs from stolen cadavers and selling them on the black market.
