On a trip around the world, every day feels like Saturday. A MAP FOR SATURDAY reveals a world of long-term, solo travel through the stories of trekkers on four continents. The documentary finds backpackers helping neglected Thai tsunami victims. It explains why Nepals guesthouses are empty and Brazils stoplights are ignored. But at its core, SATURDAY tracks the emotional arc of extreme long-term travelers; teenagers and senior citizens who wondered, What would it be like to travel the world? Then did it.
