An overall grim story about three Guatemalan kids on their journey to "the North". All of them were non actors with minimal training which results in belivable performances and the credits, well... there are thanks to over 700 people which were featured on the countless train-rides they undertook. None of the kids are actual immegrants so they went back home after this and I commend the team on the plan of donating the ticket money to fondations setup to help these people. That said I'm not enterly with them on the message the film wants to send but there certainly is an immegration problem.
