The year is 1954. A white woman's body, stuffed in a coconut bag, has washed ashore in Otatiti, Trinidad, and the British colony is rife with rumors. In two homes, one in a distant shantytown, the other on the outskirts of a former sugar cane estate, two women hear the news and their blood runs cold. Rosa, the white daughter of a landowner, and Zuela, the adopted 'daughter' of a Chinese shop owner used to play together as girls - and witnessed something terrible behind a hibiscus bush many years ago.
