What the dragon keeps / The Dragon’s Treasure - A journey from Tango to Rock & Roll

A man finds the love of his life but after only a couple of years of happy marriage the woman is killed in a train accident. The man leaves his earlier life behind and starts a self destructive journey through the oceans and deserts, but instead of killing him the pain only makes him stronger. He would like to die, but instead of the journey takes him to a parallel universe, where he has to fight a dragon.

EDIT/addition by Javier:

Unable to accept the death of his wife, a man sets himself to destroy Distance and Absolute Evil in order to reunite with her. He roams the earth looking to understand evil, and how to find it and destroy it. His journeys help him form a living breathing Dragon that he can kill.
A man's quest for Absolute Evil, his fight against it, his success, and its aftermath, intended to begin (musically) as a Tango - while presenting all of his pains and all the pains he witnesses in the world - and slowly turn into Rock & Roll as he decides to find Evil and rebel against it.
