At first, the 55 year-old Ellen (Charlotte Rampling) is willing to share Legba with the recently-arrived Brenda (Karen Young) who had sex with the then 15 year-old Legba three years ago and experienced the first orgasm of her life. She's been unable to get him out of her mind since and has returned, impelled by motives she, herself, is not clear about. But Legba can escape the realities of life under the Duvalier family only for so long.
This is a clever and nuanced movie definitely worth watching. (As an aside, I tried to find out what has become of Cesar since the movie but my Google search yielded few clues except that he now lives in Europe and appears to have had a bit part in Pierre Scholler's 2011 political drama, The Minister.)
