This story begins on a bus to the south of Argentina, when Diego and Anna embark on a year-long trip from Argentina to Mexico. It ends in China, six years later, on a double bicycle that also carries their son. Along the way, they meet very different people. On the way, they abandon their habits to open up to new horizons. They also question what they have left as much as what they have found, and about the very essence of the journey and of life.
