The coins in Santiago’s hand are meant for the bus fare back to his abusive abuela’s house. Except he refuses to return; he won’t be missed. His future is uncertain until he meets the kind, maternal María Dolores and her young daughter, Alegría, who help Santiago decide what comes next: He will accompany them to el otro lado, the United States of America. They embark with little, just backpacks with water and a bit of food. To travel together will require trust from all parties, and Santiago is used to going it alone. None of the three travelers realizes that the journey through Mexico to the border is just the beginning of their story.
