A man discovers a deadly secret when he tries to find out who killed the woman he loves in this suspense drama based on a novel by John Le Carré. Justin Quale (Ralph Fiennes) is a low-level British diplomat who has been given a new assignment in Kenya. Justin's wife, Tessa (Rachel Weisz), is an activist with a keen interest in issues of poverty and social justice; Justin urges her to avoid getting too deeply involved in the people living in Kenya, who are constantly dogged by poverty, but she shows little interest in obeying these instructions. This isn't the only area where Tessa has disregarded her husband, who suspects that she may have had an affair - for she started spending time with a handsome doctor once they settled in Kenya. One day, Tessa disappears, and is found brutally murdered; officials believe that she was murdered by the doctor after some sort of argument. However, before long Justin becomes convinced that there was a larger scheme that led to Tessa's death, and he begins digging into areas where he's not especially welcome, given his reputation as a man willing to let the wealthy and powerful do as they will. The Constant Gardener was the first English-speaking feature from Brazilian filmmaker Fernando Meirelles, who directed the international success City of God.
