When Mauricio Palos (San Luis Potosi) went to London for the first time, he was denied entry on suspicion of immigration. Four hours later he was deported back to Mexico. During his layover in Texas, he was legally restricted from stepping into public areas and was detained in a cell at the Dallas Fort Worth airport. This was the starting point of a body of work that concentrates on those people who seek a better life. On the way home, Palos started reading about the Central Americans who travel to the United States in freight trains. As the project developed, he began to realise the complexity of the subject, eventually resulting in four years exploring why Guatemala, Honduras and El Salvador expel thousands of people in search for another kind of life.
