Angel's Egg takes place in a desolate, surreal world devoid of everyday life. The environment is dominated by strange and ominous phenomena, including floating orbs containing statues of goddesses, and abandoned army tanks that seem to move of their own accord. A young girl's daily routine involves caring for a large egg and foraging for food, until she meets a man carrying a cross, who becomes interested in her identity and the nature of her egg. Together, they explore the broken landscape, discussing the meaning of faith and the origins of their lives.
