From the film’s website:
The film centers on the story of David, a straight-A student from Colorado who was sent to Escuela Caribe in May of 2006 after coming out to his parents as gay. Like many others, David was taken in the night without warning by a “transport service” and was never told where he was going or when he would be brought back home. While at Escuela Caribe, David had no way of communicating with any of his friends or family back home until the filmmakers arrived and he decided to ask them if they would smuggle out a letter that he had secretly written to his best friend.
Parents who do this to their kids wonder why they commit suicide. So sad.
