This documentary follows a year in the life of 11 year-old Kimberly Torrez to see what it's like living between two worlds. She lives steps from the border in Nogales, Mexico and crosses over each day to attend school in Arizona. Her American father is unemployed, ill with Hepatitis C, and in need of a liver transplant, while her Mexican mother is barred from the U.S. The family is on the edge, but Kimberly is holding it together and soaring at a school that is used to teaching "transfronterizos" (people who cross the border daily).
