A pseudo-documentary, “Samarang” tells the story of lowly Ahmang (Captain A.V. Cockle) and his socially superior love, Sai-Yu (Theresa Seth). Both live in the village of Samarang in the Indian Ocean. Because Sai-Yu is the daughter of a chief and Ahmang is but a poor fisherman, he needs to increase his wealth before asking for her hand. Thus he accepts the perilous offer of the wily Chang-Fu, who seeks pearl divers. Ahmang must brave the treacherous waters of the Forbidden Lagoon of Sakai, home to bloodthirsty cannibals, killer sharks, and a monstrous grasping octopus. Sai-Yu and Ahmang’s younger brother Ko-Hai come along for kicks, too. Ahmang finds his pearl, but he and Sai-Yu are stranded on the island, where they befriend a local orangutan. When they return to the boat, a shark kills Ko-Hai, and Ahmang must get revenge.

A modern geisha travels through Japan trying to find a job as entertainer, and ends up by finding love and a job as ama, a pearl diver.
