When a British diplomat's wife -- a socially-conscious lawyer -- turns up dead in Kenya, he sets out to find the truth surrounding her murder. In the process, he finds out that his wife had been compiling data against a multinational drug company that uses helpless Africans as guinea pigs to test a tuberculosis remedy with unfortunately fatal side effects. Therefore those who may have had the most reason to silence her are closer to home than he ever imagined.
