Desc: The Dark Side of the Sun: Directed by Carlo Hintermann. With Meghan Elyse, Caren Mahar, Dan Mahar, Katie Mahar. A rare and lethal illness, Xeroderma Pigmentosum, forces a few children to live far from the sunlight, in a complete isolation. But this doesn't happen at Camp Sundown, a summer camp held in the State of New York where children who suffer from XP can gather and play at night, hoping for a normal life.
