Late at night in the modern city, an ordinary male nurse on night shift is dragged into a bizarre cult sacrifice ritual. He is chosen as the offering to a legendary free-spirited goddess. With a single kiss, five divine eggs are planted inside him. The goddess vanishes right after, leaving him alone to carry the eggs.
His belly swells, and he eventually gives birth to the five eggs. Soon he is captured by cult members, tortured for clues of the goddess. One after another, the eggs crack open. Five children emerge and rapidly grow into towering giant infants. They wield powers and outwit the cult together to rescue their father.
When the five siblings burn out all their strength and pour every last bit of their essence into him, the dormant power sealed inside the nurse awakens.
