Accomplished film shot and set in Haiti based on local voodoo practices and folklore.  It is the 1960s Haiti as well as a boarding school in France where a schoolgirl, Fanny (Louise Labeque) dabbles in voodoo to settle her problems.  

The film begins with what is supposedly based on the real-life story of a Haitian who suddenly collapses on the street and turns into zombie when buried.  He is dug up and forced to work in a sugar cane plantation.  There is a preachy and lengthy segment at the start regarding colonialism and cultural mis-appropriation.

 It is a slow burn but director Bonello (born in Nice who also directed SAINT LAURENT) captures the atmosphere and superstition of the locals.  A sort of coming-of-age story mixed with a little horror and suspense that occasionally works.  A minot hit when the film premiered in Cannes this year.
