Build a movie plot around this: What happens to the professor after finding the gravestone? He has a heart attack and enters the afterlife.
A:
An archaeological team, digging in a remote village and led by an old professor, unearths an old Roman artifact, a gravestone bearing some mysterious inscriptions. When realizing that they have stumbled upon something precious, he collapses with a heart attack. Seemingly dead for people around him, he finds himself in a sort of afterlife state and realizes that the stone marked a passage into the classical underworld so he starts mingling with the antique spirits of the dead. The spirits themselves appear just as silly and petty as the peasants from the village above them, and in their desire to see what happened to their descendants, they find themselves surprised by the modern world of the living.
