St. Nick (2009)

Synopsis
St. Nick is the story of a brother and sister on the run. He's eleven, she's nine. They've left their home for some unknown reason, and are living in the woods, hiding in barns and sheds, doing what they can to survive. As the bitter Texas winter sets in, they strike up residence in an abandoned house and, for a brief, bittersweet period, manage to escape the harsh realities of their circumstances. ~sxsw.com
