In 1944, in a raft to the Tuasiva Island, the Marine Corporal Allison Awakens in South Pacific, where he meets Sister Angela. She tells him that while seeking the priest, the runaway boat to Fiji Island may be the man from the island and left behind her. Stranded from the island, however with water, fish and fruits, their life finishes as soon as the Japanese arrive to build a base, forcing Allison and the nun to cover in a cave. The primitive sea falls in love for that nun and offers the supply for their success.
