Which Way Home is a documentary that observes child migrants who are traveling without adult supervision. The children leave Mexico in an attempt to get to the United States. Two of the children are as young as nine-years-old, and are traveling in a bid to reunite with their parents who live in the US. One child was being transported by smugglers, but they abandoned him and he ends up in a Mexican prison. The movie paints a realistic picture of the harrowing journey these children undergo as they try to change their lives, reunite with family, and leave poverty and slums behind.
