What might a young girl be driven to do if she thought she had the power to change what lies ahead? Later in life, Juan Diego embarks on a journey to fulfil a promise he made in his youth. It is a long story and it has long awaited an ending, but Juan Diego is unable to write the final chapters. This is the story of what happens when the future collides with the past.
