Angel's Egg (1985) 4K & Blu-ray Collector's Edition

In a submerged city, a young girl continues to care for a large egg that she holds preciously in her arms. She believes it is the egg of an angel. A boy with a huge gun alights from a peculiar chariot. He is in search of the bird he saw in his dream. In an abandoned city, it seems as if a faint sense of sympathy has developed between the two.
