A married couple grieving the recent death of their little daughter are in Venice when they encounter two elderly sisters, one of whom is psychic and brings a warning from beyond.

Laura Baxter: One of your children has posed a curious question: if the world is round, why is a frozen lake flat?
John Baxter: That's a good question.
Laura Baxter: [flipping through book] Ah, here it says that Lake Ontario curves more than 3 degrees from its Eastern end to its Western end. So frozen water really isn't flat.
John Baxter: Nothing is what it seems.
Laura Baxter: This one who's blind. She's the one that can see.
Bishop Barbarrigo: [while passing by a dilapidated church] The churches belong to God, but he doesn't seem to care about them.
Heather: One of the things I love about Venice, is that it's so safe for me to walk.
John Baxter: Steps.
Heather: Thank you... The sound changes, you see, as you come to a canal. And the echoes from the walls are so clear... My sister hates it.
John Baxter: That's too bad.
Heather: She says it's like a city in aspic, wrapped over from a dinner party, where all the guests are dead or gone.
John Baxter: Christine is dead. She is dead! Dead! Dead! Dead! Dead! Dead!
Laura Baxter: Your bishop makes me feel strange.
John Baxter: I imagine he makes God feel less than immaculate.
Inspector Longhi: The skill of police artists is to make the living appear dead.
Heather: Fetch him back! Let him not go!
