Threatened

When he was a boy, Luc's mother would warn him about the "mock men" living in the trees by their home -- chimpanzees whose cries would fill the night. Luc is older now, his mother gone. He lives in a house of mistreated orphans, barely getting by. Then a man calling himself Prof comes to town with a mysterious mission. When Luc tries to rob him, the man isn't mad. Instead, he offers Luc a job.
