Simone is the last Greater Bamboo Lemur in Ranomafana, a protected rainforest in south-east Madagascar. After a happy start in life, surrounded by family, Simone finds herself alone, as members of her family disappear one by one. Three years on, and she’s still alone - a social animal, a primate, just like us; how has this isolation affected her mental state? Through primatologist Dr. Patricia Wright and researcher, Alba Schielen, we witness Simone’s desperate bid for companionship, as she takes a bold step for survival. At last Simone is happy again, but is all as harmonious as it seems?
